My view is that the Rich - those earning $400k and above annually can be generous and pay more taxes.
Whether they can afford to pay more in taxes is not the issue. The bone of contention is why they should be made to do so in the first place.
We've all been through the school system and most of us worked hard to score A+ in all subjects because good grades gave us more options and laid the foundations for a successful career.
Now imagine all those who scored 95 marks or higher having to give away 30% of their marks to the lazy and dumb asses in the class
So If you scored 95, you'd have to hand over almost 30 marks to some guy who only achieved 20 marks so he'd end up with 50 marks despite not having bothered to study for the exam while you burnt midnight oil to score 95 and the marks redistribution system designed to make things "fairer" for all meant you were left with 65 marks only.
Would you bother to make the same effort to achieve excellence come the next exam with this sort of system entrenched? I certainly wouldn't.
Mankind did not evolve by trying to achieve equality. The human species moved forward because of fierce competition over limited resources. The end result is that there are winners and there are losers. That is the way it is supposed to be.
