> Again, they are not part of the capital class.

I vaguely remember reading something recently, probably by Branko Milanović, about how there is a class of workers in the tech sector who earn so much money that they are gradually starting to become capitalists. When you have so much money left over that you can start putting your capital to work for you, you cross that very line. I don't mean a home savings plan or ETFs or anything like that, but if you have seven figures and can skim off returns that you could live well on, then you're definitely no longer working class.
