It's always funny to see presumed left-wingers suddenly argue that people working in degrading jobs where they get exploited is a great thing. I guess that mostly just applies as long as the people doing the work are coloured women rather than white middle-class males.
It gets extra funny when Lief himself compares it to working in coal mines.
Left-wingers are opposed to working in coal mines? The idea is to remove the aspects that are degrading and exploitative. Legalized prostitution, if implemented properly, achieves this.
