That is an absurd example. Did women, people with glasses, brunettes, and Chinese men have jobs before it was illegal not to hire them? Yes? Then your hypothetical is silly.What if it was every employer, or nearly every employer?
Yes, I would still have these principles, and I don't believe in a minimum wage, anyway. Price floors are really bad for the economy in general and the poor who want to work especially.If you were born into one of those target groups and then couldn't get a job, would you still have these "principles"? Would you happily resign yourself to a minimum wage job because "the employers can pick who they want"?
