There’ll be all sorts of caterwauling when, in Tuesday’s federal budget, the high-income earners’ superannuation tax lurk will be severely dented to the tune of a couple of billion dollars or so. The objectors, many being life-long conservative voters, will declare that they will never vote Liberal again. They will assert that a Liberal government has once again abandoned its principles in order to solve its budgetary problems by adopting the socialist stunt of penalising success and the thrifty in order to reward failure and the indolent.
