He's acted consistently with his beliefs. If he believed people would voluntarily pay more taxes, then he wouldn't be demanding a law to force them. If people gave what was needed to society willingly, then welfare programs wouldn't exist.Why did you just bring up his Ivy League background? What difference does that make? Does it take a ivy league education to see that he should act according to his beliefs?
As for the parent issue, he feels the money is extra, not needed, it wouldn't be irresponsible to pay more on that ground.
Obama partakes of the same self-interest as everyone else in society, because neither he nor anyone else has strong personal incentive not to. Doesn't mean that self-interest should be allowed to continue if it compromises the continuation of the nation.
I bring up his Ivy League education because that background can foster a certain attitude about irrationality.
