Nothing recent, but they've controlled these for a long time.
I know what you mean by capitalists, but respectfully, I think you dilute your argument to phrase it that way. Many people start their own small businesses and find success, personal freedom, fulfillment (I mean they also find challenges, anxiety, and struggles, sure.) Isn't it capitalism that allows them to decide what they want to do, start something from scratch, determine their own prices?
Actually, now that I think about it, maybe you or someone else can tell me, how does starting a business in a capitalistic society differ from starting one in a more socialistic society? I'm wondering what freedoms and restrictions there are. I started out going one way with this comment but realized there's probably a lot I could learn to broaden my perspective. I really only know what it feels like to start my own business in a capitalistic society.
Capitalism in its end state would prevent the creation of small businesses. In present-day United States capitalism, if a dozen PhDs who've been working for decades in their own time and with their own money to discover something magical like cheap insulin or a cure for cancer, it is not possible for them to start an independent business selling such a product.
