Your question is worded pretty strangely, maybe you're ESL, but I'll try to answer it as best I can.
To start with, capitalism by definition is a legal money making "scheme". The word itself means "to grow with capital" or to grow your wealth and power by leveraging existing wealth and power. As for doing more harm than good with capitalism, that's largely a matter of perspective. Own a coal mine in West Virginia? Investing money in solar panels is downright sinful! Own a silicon mine in Wisconsin? Go technology and capitalism!! So to make capitalism a force for "good", you'd need to find out what are the most collectively beneficial sectors to invest resources, and convince people to follow the plan.
That second section I ~think~ is getting at how to do this without starting a war or massive financial fluctuation. This is a bit more tricky than the optimization and cost-benefit analysis of part 1.
The most obvious answer for a smooth transition is through policy changes. Get the government to make big public initiatives for investing in the optimal industries from part 1, and create subsidies to keep people there until the industries are self sustaining. The problem with this is, agendas change, and policies follow agendas. To use a thoroughly debunked conspiracy theory: what if there was a cure for cancer, but the people who make money on cancer medication hid it from the public? Well then all that medical research we invested in after part 1 would then be worthless because now that we've cured cancer, John Doe Medical Supplies and their owner, Senator Doe, just passed a bill that bans all experimental cancer drugs. So sorry. Game over for you.
The other option would be to get the population to put together this massively difficult task of re-structuring the economy on themselves. This could go well, this could start a civil war. Depends how much change you're trying to commit to at once. And example could be the "sharing economy" we've seen rise in the past decade or so. It's a very clever and mutually beneficial marriage of capitalists leveraging existing assets like rooms and cars, and consumers essentially "voting" for the sharing economy with their dollar, and happy to do so because it means they spend less money.
In the future, try to phrase questions more clearly as it helps you get more views and more importantly, answers. Hope this helped, please let me know if it did!
