>Capitalism creates increasing levels of inequality over time while nominally providing "equal opportunity" to all.

I think a better summary is that capitalism creates more opportunities for all. Not equal, just more.

It creates more food, more clothes, more libraries, symphony orchestras, skateboard parks, cars, ships, planes, particle accelerators and space telescopes than any other system we have come up with, which means more opportunities for people wanting to be pilots, captains, skateboarders, scientists or violinists.

Whenever someone has tried to remove the inequality aspect of this, it has resulted in a loss in opportunities for all. Including the opportunity to have food every day.
