You can pay migrants low wages for less expensive food, or you can pay high wages to any citizens willing to work that hard for expensive food. This is not a new dilemma, red states in the US have tried multiple times to outlaw migrant farm labor and replace it with prison labor or other types of labor, and it has only resulted in several seasons’ worth of crops rotting in the fields.

Personally, I’d want the labor to be compensated fairly with benefits and proper wages, but then I don’t manage a farm and I don’t buy expensive food.
