Since so-called "migrant farm workers" tend to be there illegally, what society owes them is a hearty punishment followed by a deportation.

Or if you're talking about the legal migrant farm workers, then what society owes them is the deportation of the illegals, so that they no longer have to compete on price with an unlimited number of people who shouldn't be there.

It's no surprise that unenforced immigration laws plus an open border to a third-world country drives down unskilled labour prices.

Heck, once we get rid of the illegals we may find that Uber prices go up too. The US doesn't really have an oversupply of unskilled labour.
