If you say that, you open yourself up to the open borders bushbot counter-argument that most people are actually doing well economically, which is true. What they miss is that we're doing okay DESPITE our horrendous immigration policy, not because of it.
All I'm saying is don't make claims that are easily refuted. Your last post was good, BTW, that's exactly the kind of argument we should be making.
I'll accept "economic drain" for now, and say that it's a disaster for America in various other ways, with the 'economic disaster' looming in the near future if the illegal immigration bill isn't completely shredded and re-written by the House in a way that stops the insane influx of illegals and deports many of the present ones. No country, not even America, can sustain this kind of free-flowing immigration forever.
