Could you please help me answer this question:

Question 1:Since the pdf mention mushroom farming, why farming is such a low-paying industry?For example,as a nearly competitive firm,there is not much room to earn above or equivalent to a normal profit of 0.This can explain why farmers work such long hours for little pay.

Question 2:Could you use the demand and supply model to look at the services and goods that are produced by low-skilled immigrant workers.
