I asked a question here about whether a city could exist out at sea.
As a more specific question about what type of people would live and grow up in such a city, I have the following questions about people who have lived out at sea for their entire life:
Would people that have lived their entire lives out on the water have any particular skills that they could then use to make money from land-dwellers?
What kinds of things would such sea-dwellers value? What would they pay good money to buy as a luxury?
Is there anything that people could do other than fish whilst out at sea in order to be able to make money from people who live on land? (Other than shipping goods/transporting people).
Would someone who has lived their entire life out at sea be able to adapt to land-living? What would they need to learn in order to be able to live on land?
