The immigration discussion is all leading to a very obvious conclusion:

1) US will close the southern border and get incoming illegal immigration to virtually 0.

2) Illegals with a criminal record - especially with a violent or repeated record - will be deported.

3) Illegals whose only crime is crossing the border will be forced to self-declare and pay a fine within a certain amount of time (12-24 months) or be deported. US will make $.

4) Once fine is paid in full, they will be given path to legal residency and taxes will begin to be collected on income  earned. US will make $.

5) Legal immigration will be revamped so processing is 10-100x faster, and rules around who can enter the country will become stricter to align closer to the goals of the US for the next 2 decades.

At this point, the US can finally move on from an absolute dumpster fire of a failure which is US immigration.
