The goal for the capitalist is domination. They say: "You don't like being a wage slave? Then you should start a business. If you're successful you can aquire some wage slaves of your own." Capitalism epouses freedom from government, but freedom from capitalists with dark triad traits has never been part of the deal.

The goal is to climb the tiers with the help of nepotism until your and your descendants are the ruling class. The ruling classes are always basically evil. Inheritance is the one thing that breaks the neat logic of capitalsism. Capitalism without inheritance could actually have a chance of working, but sadly that can never happen because appropriating inheritance would require an unjust use of force.
