Your last sentence tells it all. What good is a deportation program if one illegal is deported and 10 other cross the border illegally. Total control of the border, coasts and visas is the key.
Exactly, and that’s why our politicians muddy the water, because they keep the current system and they don’t get border control. If they get an amnesty program without controlled border, coast, and visa, then they win that way, too.
They win by border/coast/visa control NOT happening.
My guess is that they’re more than happy with the status quo.
