The fact that labor is a commodity is not negotiable. It's not "the system", nor eeeeevil corporations and their officers that declare labor is a commodity, but the laws of economics. Complaining about this is just as useful as complaining that gravity treats people the same as other objects. The laws of economics don't care that you're a person any more than the laws of physics do.
Labor, unlike commodities, can modify the market itself and artificially inflate its value. People vote, inanimate objects do not.
Economics is no a hard science like physics is. And even physics is not set in stone - it evolves, just look up the history of physics over last couple centuries.
The economical theories are about people, are made by the people and influenced by the political interests. The free market theories were created at the time when slavery was still existing in civilized countries, when child labor was wide spread, when the the leading Western countries waged war on China in the name of free drug trade and when Ireland was experiencing the famine.
Traditional Christian doctrine on economics was focused on the interest of all human beings whether they be slaves, serfs, hirelings, merchants, entrepreneurs, knights or kings. And it was worked out with fear of God. That is why after thousand of years of Christian culture the Europe (with hers outposts) rose from barbarism to the high civilization.
Free market theory is built from the one perspective - of the owner and his profit. All else is subjugated as tools and material. Free marketeers are parasites who feed on the moral/spiritual capital accumulated over several centuries.
