Labor is a small part of the total costs of farming. Large amounts of costs are in capital equipment, land, packaging, retail location selling and transportation.
If you are really worried about high priced items that affect poor people, then perhaps we should be getting more immigrants that create these expensive things like healthcare.
If you are a doctor, they should automatically approve your visa application. Lets drive down that price of healthcare! If you make 100k+, auto approval as well. More tax money please! NOT strawberry workers though.
Which people are most affected by the change in price?
