I don't have a problem with levying sufficient taxes to pay our debts (indeed, I vehemently oppose allowing our expenses to outpace receipts, and want pressures brought from both sides to reduce that spread to less than zero), but need for revenue needs to be the driver. I do not believe a person should be taxed b/c they have too much income and it needs to be redistributed, since that is none of the government's business (and if you think taxing income is a problem, let's talk about taxing wealth and see how popular that is). She or he has as much income as she has, and if you're (royal second person, you understand) trying to "take" it for the simple sake of denying it to other people, then that's confiscation and would be illegal in any other context. The first question isn't "how much do the taxpayers have?", it should be "how much money does the government need?". We never seem to get around to asking that question in a thoughtful way (b/c as RJ Karl will tell you, there's no room to cut any programs except the ones he disagrees with. Otherwise, you hate children and first responders. Or something.)
If I was satisfied that we had done a good job pruning our expenses, then I'd be in favor of raising taxes. In truth, we need to do both and the sooner the better, but the first stop has to be cutting waste and reforming so-called entitlements. It's INSANE to take money from working families to give it to wealthy retirees or to retirees who didn't save. Screw it, ACA is the law of the land. Let's crank up the death panels and start thinning the herd.
