"an easy solution: increase the number of legal immigrants we allow."

Not really.

The answer is: have a fair, transparent and function system.

Then - yes - you can totally 'increase' (or decrease) as needed.

'Increase a bit' likely the right thing to do - but it's a completely separate question.

But throwing Green Card holders out is completely insane, grabbing people out of church and schools and putting them into detention without oversight is cruel and inhumane.

The national debate is insane.

Just basic, normal, reasonable policy and process.

That's it.

Like DMV level stuff.

Then you can adjust the numbers one way or another.
