I don’t see anywhere that anybody said that. Most of them seem to want more legal immigration, because if you make legal immigration easier, fewer people will do it though other channels.

The harmful conduct we should actually be focusing on here is companies exploiting/abusing undocumented workers and violating labor laws whose immigration status chills them from reporting. Those companies are the real criminals here. The employees responsible, or who should’ve known, should see the inside of a jail cell, and fines should be an existential threat to the business if they do this with any regularity.

If it’s easier to immigrate legally, and employers believe hiring undocumented workers will cost them way more than they stand to save, we’ll see a very different dynamic.
