So, we turn away engineers, teachers, and spouses, while keeping 12 million almost entirely manual laborers whose income potential is low, and whose drag on the system and likelihood of voting for benefits instead of conservatism is high?
In a perfect world we would accept the best and brightest from overseas but you and I know we don't do that. We have a green card lottery and being the best and brightest is not a condition to be eligible.
We also have 12 million living here illegally in a big mess Congress and every president over the last 30 years created. You don't like it, I don't like it. But, it has to be dealt with.
Do you want to add to that problem by bringing in more people? That is what I think Rand is getting at. It is the only viable solution. If that plan is accepted, immigration is slowed significantly. We deal with the 12 million here.
Or, we just stick to present policy. Rand has the pragmatic approach. Best to take what we can get otherwise we get nothing.
