All sorts of people are controlled all sorts of ways, and it's not capitalism that does it. Indeed, capitalism clearly prescribes FREE markets, open exchange, etc. It's a powerful tool to uplift the poor.
No, the primary instrument of oppression is the government. Ask yourself this; who has more power over you, right now; Jeff Bezos, of the local chief of police? Which one can send an armed man to your home with impunity?
You're deeply confused about what capitalism is. Capitalism clearly and directly forbids such things as slavery; slavery is in obvious contradiction to the very concept of a free market. Likewise government suppression of labor; also not in accord with a free market.
Again, it's impossible for slavery to have been born from capitalism. Capitalism clearly directs free markets, which are in direct contradiction to slavery. Now, you can say that there were free markets and slavery which existed separately but at at the same time, and that's historically accurate, but to say that slavery is capitalistic is the product of either ignorance or dishonesty.
