I know the book and it's an interesting theory. I guess most of the 'rich' people I know / know of are entrepreneurs and they didn't get rich from capital returns but by building a company that created an unthinkable amount of value and also many jobs and success for a lot of people.

In my mind also, the best antidote to that is not taxes but anti-trust (make sure companies don't unfairly stay dominant) and low interest rates (which has been the case for a while) so that people without capital can borrow at reasonable cost.

Taxing a company doesn't make it less dominant. it can be argued that it makes it more dominant because the cost to compete with the dominant company will be higher if corp taxes are higher.
