Hmmm, I wonder if the mass naturalization candidates during the Clinton administration took those "detailed" tests of "up to 20" multiple-choice questions. Or maybe they "verbally answered" "a set of civic questions." (Check out the INS site: if you study the colors of the American flag, you'll probably pass.) There are also language waivers for at least 3 different situations.
True, children of long-time citizens know far less about American history than their parents were taught, but is that not the result of our school systems' concentration on "multiculturalism," which is in turn foisted upon us by the massive influx of foreigners?
Instead, they're assimilating to an America filled with muslticulturalism, political correctness, and government largesse, which is why immigrants are MORE likely to vote for liberals than native-born Americans (according to the 2000 election returns) and MORE likely to receive government handouts than native-born Americans (according to economist George Borjas). And this change in the culture helps explain why Hispanics and Asians are beginning to form all sorts of special interest groups, modelled after the NAACP and the like, to lobby for more goodies and discrimination against white people, which is politely referred to as "affirmative action." These changes alone make mass immigration undesirable.
And that's leaving aside the immigrants coming here with unassimilable and anti-American ideas, such as the immigrants who gave us Septmber 11. (Those immigrants, by the way, confirmed the neocon argument that immigrants are doing jobs Americans don't want: not many Americans want to fly airliners into skyscrapers)
