"This argument about government subsidies is way too fucking idiotic to have picked up this much steam."
Our country currently provides a number of benefits to people who are below specific arbitrary income levels. When companies deliberately keep their employees wages low enough that they continue to qualify for those benefits then their workforce is being subsidized by government. Hence the company is being subsidized by government.
The minimum wage was made into law decades ago when corporate abuse of employees was pretty rampant. Because their was a large surplus of labor wages could be kept very low because some other starving peasant would be willing to do your job for less because anything he got was better than the nothing he had and would stave off starvation just a little longer. Government basically stepped in and told businesses that if they wanted to continue as licensed legal businesses they would need to pay a minimum or, practically speaking, living wage.
I don't think anyone has anything against a person working extra jobs to earn more for themselves, or pooling resources with another to afford more room in the budget. A living wage doesn't affect any of that, so I'm not sure what you're going on about.
What personal liberties and choices are you talking about here? Maybe the liberty to pay a peasant as little as possible to keep them coming back while they rely on government subsidies to survive? If you want to run a business with employees then pay them a living wage so the rest of us aren't subsidizing your venture, or get out of the way so someone else can do it.
