Today’s American right is an uneasy coalition among libertarian plutocrats and working-class and middle-class whites who depend on Social Security and Medicare and can’t afford to send their children to expensive private schools.  The need to win white middle American votes means that the right can’t simply promise to abolish public services, leaving the mass of Republican voters on their own.  In order to be electable, conservatives have to abandon pure libertarian principle and accept the idea of vouchers funded by taxation — even though this is really just “voucher socialism,” as hardcore libertarians sometimes point out.  But this doesn’t necessarily harm the right-plutocrats, particularly if they can invest in health insurance, private schooling or retirement savings companies that can vacuum up voucher money.  (Source)
