Everybody is looking for a deal.
They take the lowest bid and complain about the results.
If you didn't hire them, they wouldn't come.
I realize this is simplistic, but think about it. You have an economy which depends on imigrants to do the dirty work for you. Yet you complain when these same imigrants start to impact you in a negative way. Illegals are OK as long as they do the dirty work. You get what you pay for. You want a good high paying job with benefits, but many of you shop where the goods are sold by people making a pitance and sell goods made over seas in sweat shops.
You can't have your cake and eat it too. (Any more.)
Expect less - Live more! (I just made that up!)
