These are interesting points. Regarding farm labor having fewer protections. In general, labour protections can be distortion-creating (e.g. a minimum wage) or distortion-busting (e.g. rules that ensure people are paid on time). Regarding the captive labor force: this might be bad for non citizens (and humanity overall), but it seems like it's good for US citizens, who benefit from increased (unlimited?) supply of farm labor, reducing upward pressure on food prices. If I've understood the above correctly, it seems that 'we need farm workers' isn't an actual problem that needs a solution (from the perspective of US citizens or, by extension, the US government). What have I missed?
