White House aides and some members of Congress believe that when the immigration-reform unpleasantness is behind us, conservatives will come together to back the administration and Hill Republicans in the spending fights that lay ahead. I doubt it. Amnesty for low-skilled illegal aliens comes with a taxpayer price tag of almost $90 billion a year in net costs. Although eligibility for many federal welfare programs is delayed, for the ensuing decades these low-income families will qualify for over 60 welfare programs. Just as with native-born low-skilled workers, these newly legalized workers will impose a huge net cost on Social Security — $2.6 trillion according to Robert Rector. And conservatives are going to man the ramparts because the Labor/HHS appropriations bill is over its spending cap by a few billion dollars?
