This is already done in the army In the U.S. Army, they move people from base to base all the time, not because they need more people here or there necessarily, but because they intend to prevent factions from developing within the service due to prolonged proximity. Randomly moving people around all the time homogenizes the military and protects its ...

Robert Zubrin answers this in his non-fiction book "The Case for Mars", in the chapter the "Interplanetary Commerce": Precious metals. This has already been written in another answer. Zubrin states however that it is not yet clear how abundant these are. Deuterium Deuterium is important for Fusion reactors and according to the book Martian water is ...

"All Empires of the Future will be Empires of the Mind" The economy of the future will not be in parts or in minerals - these would be obtainable anywhere and with new means of manufacture would be quite ubiquitous. Instead real value would be in tertiary items. Things like: Inventions, IP related items Art, culture, entertainment Research, scientific ...

A major food source for the people is an insect that has a similar lifecycle to a cidada where each swarm lies dormant for a number of years and emerge all at once to breed. The difference here is that that they do not have a predictable emergence time and they are only out for a few days. The people move to the region they think the next swarm is going to ...

Labour != Skills The single biggest issue I see with this proposal is that it assumes that your economy is based on goods only and that services are all interchangeably bundled up in this box called 'Labour'. Services as a rule are as much, if not more, a part of the economy as goods are and that's because you can't just interchange different people to do ...

Frame challenge: whatever policy you suggest, no matter how much evidence or argumentation you'll have for the policy, it won't make a difference. Why? She won't be listened to. 17th century society was very paternalistic, the ruling men of that age wouldn't listen to a women's ideas about such matters. A simple historical example of such a policy would be ...

Rocket Fuel. @aadv's answer mentions the key component. Mars' gravity is 1/3 that of Earth's. This means getting anything off Mars is significantly cheaper than it is to launch it from Earth, potentially exponentially so if the lower engineering requirements lead to a Martian space elevator being possible while an Earth one wasn't. So you want an export ...

Mars has a lower escape velocity compared to Earth. It also has a less dense atmosphere so there is less air drag keeping you from hitting higher speeds. Lower gravity might also make some aspects of heavy industry easier - ships and trucks being able to handle more tonnage, comes to mind. There probably aren't as many environmental issues with strip mining ...

Services. Not the regular ones, but the kind that is more aligned with sustained Bitcoin when it was released, or services to governments who want their dirty stuff done away from prying eyes. There isn't any commodity on Mars that is not easy to obtain on Earth already. Earth and Mars were made of the same raw materials, but Earth: Is about 10x more ...

Allright I'm basing it off of this: https://tvtropes.org/pmwiki/pmwiki.php/UsefulNotes/Airships Unlike what others have said, airships are actually exceptionally durable, rule of thumb for storms it can handle is an average speed the same as the maximum speed of the ship and the airship is one of the only vehicles that benefits from the square cube law. The ...

The main factor is plausibility to the audience Since the risk of non-repayment by an adventurer seems rather high, the interest rate should be correspondingly high. For D&D, 20%-50% tends to work well. In most adventuring and storytelling, interest rates are determined simply by what the adventurers are willing to pay in that town or on that ...

You don't "farm" bullets, you manufacture them. Or fabricate them. Or produce them. You want a factory. That said, people would make their own bullets way back then. Melt metal in a mold and pop them out. In fact, many people still make them themselves. For cast-lead bullets, basically all you need is the raw materials, a campfire, and molds (...

Moneylending is an ancient practice to turning static piles of cash into larger piles of cash. Here are some general trends for moneylending that have a relationship with the amount of money being lent and the interest rates. I will now point out that the kind of moneylending which is large sums of money at absurdly high rates isn't proper moneylending, it'...

Most answers so far focus on challenging the premise of the question by claiming it would not be as expensive. I will try to answer the question within the original framework, which assumes that there is a plausible in-universe reason for the technology to be too expensive for the average middle-class worker. Under that condition, the technology must be ...

Energy. Let's assume in your scenario Mars is populated way less densely than Earth. The would easily be able to harvest more energy than they need and share it with the earthlings. Ways of harvesting could be: Solar. While the distance between the sun and Mars is about 1.5 the distance between sun and Earth (meaning that the raw amount of sunlight ...

Gold and other precious metals/commodities. Imagine Earth, but never mined. In the past it was possible to find surface deposits of ores made of more than 15% grade precious metals. All known of those have already been extracted. Finding a deposit that is 1% copper is usually very profitable with current technology. I did the math once (I'm willing to put ...

Certain books. The kind that teach how to build stuff. How to make concrete. How to build a forge and make tools. How to make gunpowder and a alcohol still. How to fix a car and how to make a electricity generator. Even today, these books make a very small percentage of the total amount of books. Libraries are full of self help books about building a ...

Main Issues The principal issue I find is, first and foremost, you'll never have a blimp big enough. For every person or thing or load of groceries or increased battery / solar panel capacity, you need ever more lift gas which means you need ever larger ship size. The longer you want to remain aloft, the more fuel, the more groceries, the more fresh water ...

Since you are asking about the high level factors, let me try to give you my take on economic theories (but take for granted that economy is not an exact science, else if all the theories economists have would be correct, they would get their income by speculating in the stock exchange, not writing book of economy where they explain why their past forecasts ...

Airships need ballast and lifting gas to maintain their altitude. Water is reasonably cheap, just heavy. Hydrogen is flammable, so the other option is helium which is expensive. This will be much more of a concern than food and drinking water. Airships don't do well in storms. Good airship captains solve that by never flying into storms if they can help it, ...

Wood. On the future earth, forests are gone. Wood is difficult to grow because suitable land is dedicated to edible and fiber crops, and locking up land to grow desirable hardwoods is no longer feasible. But people still treasure things made of wood. Mars has thick forests. Absent insects and diseases, trees grow fast in the terraformed Martian soil. ...

I'm going to take @Willk's controlling AI a step further. Quite a few steps further. Remember the story (*) of the Christmas Truce from WWI? There were often informal cease-fires on Christmas and Easter, but on one battleground the troops took it to another level. They met up in no-man's land, shared drinks, swapped souvenirs, sang carols together. ...

One option would be if there was a plant or animal species that had a non-annual boom and bust in population. Some plants, like onions for example, have a biennial life-cycle. Some animals have population booms staggered over longer periods, such as cicadas. So a social group could form who specialize in harvesting such a crop/species. For example, group X ...

Instead of indentured servitude, go to the opposite extreme; everyone is an at-will freelance employee in a job-scarce industry controlled by a few corporations. Unemployment is high. If you have a job, you hang on to it and, if you don't, you go wherever the work is. Corporations know that people are desperate for jobs and will travel to get them, so ...

Differing abilities Some people are better able to do whatever the task is. But it's hard to tell who until someone actually tries. So there is a constant stream of people being added to the location to attempt it. And a constant stream of people leaving who failed. Differing sensitivity Some people have an allergic reaction (or similar) to something ...

The artificial womb's impact on society is one of the things explored in the background of Lois McMaster Bujold's Vorkosigan series. It's definitely a liberatory technology for women, even more so than the washing machine or contraceptives. I can think of a few scenarios: Amortization Every technology starts out expensive and gets cheaper over time. The R&...

They would totally work in arbitrage with total approval of the government --- reducing volatility, they lower the average cost of borrowing across the market and thus provide a useful service. I was always abhorred by the idea of arbitrage (literally making money from nothing; boils down to having an internet connection and hardware that's a few ...
