Of course, I can refuse to take a job, but then guess who starves to death? You can hardly call it a choice when the alternative is death. The only truly free markets are ones consisting of syndicates and workers' councils. Every man should be his sole master. Wage slavery is America's greatest threat to liberty.
Well, how is the world supposed to function if there aren't businesses looking for workers, and workers looking for work? It's not like workers are powerless anymore, this isn't the 19th century: workers are able to unionize, and pressure business according to their own wants and needs.
As you put it, if you don't take a job, you'll starve. In many cases this may be true, but again, there is nothing stopping you from buying or leasing land and growing food on it. Unlikely scenario for this age, but still, an option.
From what I'm reading, you're essentially advocating worker-owned businesses where each individual worker owns a stake in the company, and is his or her own boss? There are businesses like that, but there will always be a power hierarchy with the workers at the bottom and the CEOs at the top. Unless there is some massive push by people to change the way the world runs, which I doubt will ever happen due to the inherent laziness of Man, then there wont be some utopian economic dream system.
Even if there are flaws, you still get to choose what cog you are in the machine.
