Trump's plan was a big, stupid wall that Mexico was supposed to pay for. He talked about it like it was magically going to fix illegal immigration. Did it work? Obviously not, just like we all explained to you.
I think if we really want to fix the issue, we just mandate e-verify and we give severe punishments for the employers who willingly hire illegal immigrants. It's pretty simple - they're not going to come if they can't find work here.
Biden is at least bringing up going after the employers. But we'll see if anything actually happens with this. I'll believe it when I see it.
