Capitalism isn't about making as much money as possible
Well, it is. It's certainly not about trying lose all your money as fast as you possibly can. Capitalism is about making money, first and foremost. Everything else is simply a discussion of the methods.
it's about letting the market decide prices rather than artificially fixing them. And then using the market to make as much money as possible.
If a company agrees to pay its supplier a higher price, how is that "artificially fixing"?
Government-imposed minimum wage levels are a classic example of "artificially fixing". But since fair trade prices are established by voluntary mutual agreement (and not by the forced imposition of prices by a regulatory body) there is no "artificiality". It's just a classic case of letting the market players decide. Pure capitalism!
