I've never ever heard of a "single capitalist" taking advantage of an entire race. You sound like a Marxist when you say that. OED has a fine definition of capitalism that will help you out here. You can't possibly know what a capitalist is by suggesting such a thing.
When someone makes a choice to take a lower wage, it's usually because they can't get anything better. Guess what? Capitalism implies (and I really do mean implies) competition. The minimum wage (originally lobbied for by white unions) means companies are restricted to hiring only those who can produce more than that minimum. For the "stupid poor minority" you're so hell bent on "protecting", this means making it far harder to gain experience and work their way to the middle class. (You know, like immigrants used to do.) Instead, they're paid not to work via welfare programs (meant to make things "easier" right?) and not allowed to work off the books while living off of others.
Also, you're going to have to say it again if you seriously want to stick to the point that unions have no bargaining power. If this is the case I'll be less "strong" (lol) and we'll do this at a lower level. I'll write you up a whole 10 page step-by-step paper on all of the opportunity cost losses that you'd create if, theoretically, you were in charge of the economy. Hell, if you are indeed a Marxist or even socialist I'd be happy to give you the "See Spot Run" version of what subjective value and economic calculation is.
