So the extremes we see today must be the natural extension of that process... right?
But that is equivalent to saying "When I work out, I get stronger and more muscular - therefor body builders and power lifers must have gotten to where they are just by working out even harder, for more years" - neglecting that all of the top athletes have some degree of genetic gifts, professional coaches, extremely strict diet plans, and most use some form of biochemical assistance that would get them banned from most professional televised sports.
The State is the coach, diet plan, and performance enhancing drug of capitalism.
But what we see today is a massively tilted field, and that is due to specific policies and laws and rules that - although we take many of them for granted - are choices we, as a society, have made. Choices which we could change any time we, collectively, decide to.
