As Vincent Gallo put it recently re: federal debt:

> The USA can tolerate one of these two things. A system of no welfare, no social services, no socialized medicine, food or housing with open borders. OR. No open boarders and highly limited, highly controlled, assimilating immigration policy. We cannot have both. When the USA had unlimited immigration over 100 years ago, we did not have Government supporting immigrants with welfare, medical services, housing, food etc.

I don't agree with Mr. Gallo here - I'm just sharing what a popular RW response is on this.
