Here is why I have no problem with the wealthy paying higher taxes: because like it or not in this country money buys more then physical items. Rich people flat out get away with shit ordinary people can't, and when they do get caught a lot of times they are not punished as severely as an ordinary citizen. It's also usually the wealthier people who know how to weasel out of paying anything via tax loopholes, etc.
Of course not all wealthy people behave this way, but it's not a rare thing to see people with money getting away with crap nobody else can. Just look at the 16 yr. old who got away with killing several people while driving drunk by arguing his parents had not taught him the difference between right and wrong.
