This has been my problem with the path to citizenship for millions of immigrants -- our welfare state can't handle the extra burden. It does no good for the Left to rage about how Hispanics are hard working and eager to succeed -- that's not the point. In this economy that statism has suppressed, the new citizens won't find jobs to support a family, and they'll have live on welfare benefits.
If we created a free market and depended on private assistance for emergencies, the economy would likely support millions of immigrants, but not this economy. This immigration bill is insane given our economic situation.
