You don't think that a post scarcity world would provide opportunities to wield power over others? People will always build heirarchy, we're wired for it.
This is something that pisses me off about anti-capitalists. They talk as if money is the most important thing and want us to all be equal with money, but they implicitly want inequality in other even more important areas like social status. Capitalism at least provides an alternative route to social status instead of just politics, making it available to more people, not less.
Agreed. In that world, fame and power becomes more important since wealth no longer matters.
