Amnesty would indeed be fatal to the American way of life as we have long known it.
I know, it is supposedly "xenophobic/racist to oppose immigration-- the same things were said against the waves of Irish, Jews, Italians, etc., who arrived at the turn of the 20th Century."
Well, actually, Virginia, there IS a difference...and America is a very different place today.
Most ILLEGAL aliens are undereducated poor Indian Hispanics. The guvment's own data tell us that the social pathologies of such are horrendous-- the poverty is likely to remain entrenched, hence guvment dependency, together with pathologies such as very high rates of illegitimacy (70%), dropouts, crimes, gang proclivities, barrio blight, a willful clinging to Espanol (which DOOMS assimilation) and 5 TIMES the rate of alcoholism.
Also, when Europeans came in a great wave 100 years ago, they had higher aptitudes and came to an America where educational level was FAR LESS critical. We are now an advanced service economy where education is CRITICAL to escape the highly addictive drug of guvment dependency.
