Yes, it is very convenient that NPR picked a type of produce that demands relatively high hourly wages so that labour would look greedy in this circumstance. But make no mistake, the exact same thing will happen on farms with much lower hourly wages where the same level of skill isn't required. As for your second question, you and I both know the answers are difficult. Do you think it's reasonable for American labourers to make the same as a labourer in Peru? Because that's the issue here: globalized trade causing a race to the bottom in labour compensation. IMO there aren't many great answers, but "pay people a Peruvian wage in the US" certainly isn't a good one.
