Our family has a small farm, my parents didn't think we did enough of that and put me in a white van full of migrant workers at 12 years old (hey the 80s!) to go pick produce in a field all day... It was grueling work but I got a first hand account of migrant farm workers and the way they are treated.
A worker that does not put up with petty BS is surely less likely to put up with major BS (like wrongful termination when getting pregnant or whatever).
Not to mention the chance that you'll be found out by the authorities; I want to believe the punishment for wage theft is much more than the savings. Of course, that depends on how many people report it and how much evidence can be retrieved I suppose.
There's no justification in being shitty to your fellow citizen over this paltry sum of money. None.
Can't buy your way out moral bankruptcy with $10,400 over 2 decades.
