Capitalism doesn't profit from free markets, Capitalism is synonymous to free markets, and there was no such question. Just to recap:

Capitalism/free markets is the idea that profits above all else is beneficial somehow for the largest number of people. As an ism it fails completely at delivering on that though because while puts people to consider everything in terms of overhead vs profits it leads to people doing ungodly things, just to profit, or maybe break even, this goes for both employers and their employees and the results are strife and poverty. Free market means that if a worker gets injured on the job the employer is free to replace them with another worker, no obligation exists in that Ism to the worker. The largest and longest depression happened while the People of world over experienced the "free markets" theory in the 19 century, the Laissez faire century where regulatory bodies did not interfere with the markets, and it demonstrated what a bunk theorem as far as "bettering everyone" it was, again and again. Back to the basics:

Free market capitalism says that I may employ whomever I wish, and equally refuse to employ for whatever reason, whomever I please, equally if my employees hurt themselves of no fault of my own, I should be free to find new employees and say fuck off to the broken ones, exploiting is the M.O. of Capitalism at its finest and purest after all. Ultimately you are an imbecilic, no spine, troglodyte because your repeated refusals to discuss the pertinent issue, the issue regarding a surplus of workers competing for ever decreasing wages, so you can keep putting together nonsensical questions that you think have any relation to the deprivation I'm speaking about, where workers whore themselves to the highest bidder and employers reap the benefits of such a surplus of workers, because I'm thoroughly convinced that you're as imbecilic and idiotic as they come as you're thinking you can evade or deflect from it with your utter idiotic nonthought questioning.
