Congress can debate immigration laws on the books, but this cultural shift seems to be something else entirely. Instead of measured enforcement, it appears to be the normalization of cruelty. We're punishing people who are part of the workforce contributing to our country's economic output.
Seems like the real question is, what do we get out of this? Because it doesn't appear to be aligned with security or prosperity. It's just needless suffering, bureaucracy, and wasted resources.
Deterring irregular economic migration? If the government adopts a non-formal policy of not prosecuting non-criminal non-violent workers, it's implicitly saying it's fine to people to violate immigration laws and come here to work, as long as you don't cause trouble. You might think this is fine because free movement of labor is good or whatever, but that's not what most Americans want.
Note that what I said was that most americans do not support "it's fine to people to violate immigration laws and come here to work, as long as you don't cause trouble". That's not the same as "ICE raids as currently implemented" or even "don't offer current pathway to citizenship for current undocumented workers".
