Your freedom to do those things under capitalism is wholly bound by your existing wealth, and wealth begets wealth. When your parents are well off, you can get into good schools, get better education, and ultimately get a better job and, really, be a better worker bringing more wealth into the already existing pool of wealth your family had. Those who have been disenfranchised by way of things like eminent domain, redlining, or the straight up prosecution of them and their fellow men simply don't have that option to rise up. They don't even have the opportunity to try and fail, they've failed by their very existence. At a macro scale, once you've reached the top (e.x. Facebook, Google, Amazon, etc.) you have the resources to not only out-do any of the competition but to sell products at a loss to starve your competition and bully them into submission, which big companies do all the time instead of investing in better products. It's just good business.

Circumstance plays a lot into how much wealth you start out with and how much wealth you end up being able to accrue, so while it's nice being not even at the top but even just the middle, it's important to have the mindfulness to know that there are those below you who don't have the same freedoms, and they're not there because their businesses did poorly. Some of them are, but most are simply victims of greater powers stealing their capital.
