Poverty is no longer so clearly delineated either. In an underground economy where wages are often in cash and tax-free, and entitlements easier than ever to obtain, well over $20 billion a year in remittances are sent southward to Mexico alone, maybe double that sum to Latin America as a whole.
Something here once again has proven illiberal: Does a liberal-sounding but exploitive Mexican government cynically encourage its expatriates to scrimp and save in America only to send huge sums of money back home to help poor relatives, so that Mexico City might not? In turn, do an increasing number of illegal aliens count on help from the American taxpayer for food, housing, legal and education subsidies in order to free up $20 billion to send home?
The paradoxes and confusion never end these days. Do today's immigration activists work to grant amnesty on the basis of legal philosophy and principled support for open borders, or just because of shared ethnic identity? If there were now 11 million East Africans in America illegally, would today's Hispanic immigration lobbyists seek amnesty, bilingual services in Swahili, and yet more illegal immigration from Kenya and Uganda? Would they ever seek racially blind legal immigration into the U.S., based on education and skills rather than point of origin?
The yearly arrival of hundreds of thousands from Latin America, mostly without English-language skills, a high-school diploma and legality, has also challenged old ideas of everything from the assessment of U.S. poverty rates to affirmative action. Once an impoverished resident of Oaxaca crosses the border, does his lack of education and his modest income immediately help cement the charge that the American Latino population has not achieved economic parity?
Or, in the first nanosecond after illegally crossing the border, does a Mexican national or his family in theory become eligible for affirmative action, on the basis of past historical underrepresentation or present-day discrimination or poor treatment in Mexico -- in a way not extended to the Arab-American or Punjabi-American citizen?
Why does the present administration oppose new anti-illegal immigration laws in Arizona and Georgia that are designed to enhance existing federal law -- but not so-called "sanctuary city" statutes that in some municipalities deliberately contravene federal immigration law?
The old liberal ideal of a racially blind, melting-pot society where the law is applied equally across the board has descended into the new postmodern practice of enforcing many laws only selectively -- and based entirely on politics, matters of race, ethnic chauvinism and national origin.
In sum, yesterday's immigration liberals have become today's illiberals.
