If more humane border is feasible for preventing illegal crossing then that’s of course good. I wonder what would need to happen in the US to make the border effective, if it is even possible.
And even better than any of these: we need to actually give fair hearings for asylum seekers.
I think that’s often brought up in Europe how illegal crossers circumvent the system and “skip the line” for asylum seekers, also hardening the attitudes towards them. Better border control and more proper asylum seekers would be good.
