@RegalBeagle deportation is indeed a problem, especially if you cannot prove nationality of the illegal. and if you claim some kind of refugee status, UN steps in. so once you open the borders, it is very hard to get rid of them. unfortunately. it was an evil plan to begin with and very hard to battle.
@RegalBeagle yeah, you are correct. that is what governments do - they want you to do something so they make it easy and if they don't they make it hard. that is how covid 2020 was as well. it's not like we were enslaved and locked up but things were made to be easy or hard. TFM says that if you cut welfare to foreigners, they will self-deport. so it is tried and true approach the governments already use.
