The high-skilled worker is not stupid and knows that’s exactly what you’d do. He will do a bit of organizing first, convincing decent, caring people that low-skilled workers are being exploited and not earning a living wage and that Congress should enact a minimum wage in the fencing industry of at least $20. After Congress enacts a minimum wage of $20, what then happens to the chances of a high-skilled worker’s successfully demanding $55 a day? They go up because he’s used the coercive powers of Congress to price his competition out of the market. Because of the minimum wage, it would cost you $60 to use the three low-skilled workers.
The minimum wage not only discriminates against low-skilled workers but also is one of the most effective tools of racists everywhere.
Whether support for minimum wages is motivated by good or by evil, its effect is to cut off the bottom rungs of the economic ladder for the most disadvantaged worker and lower the cost of discrimination.
