Why aren’t republicans tired of paying more taxes because the rich don’t pay their share?

According to the IRS, the top 10% pays 28% of all Federal income tax.

That seems MORE than fair to me.

What percentage of the nation's wealth does that 10% have?

That's an unfair metric. Wealth is assessed in a myriad of ways, not all equally taxable.

Well keep scratching those lottery tickets. I’m sure one day you will be rich too and avoid paying your taxes like the IRS estimates at about 1 trillion dollars a year from the ultra rich and corporations.

Avoiding illegally, or by any of a myriad other means (reinvesting to report low net financial gains, filing as a certain type of corp., etc)?

They aren't paying because Congress has cut funding to the IRS and auditing the rich takes expertise and time. But go ahead and swallow that you personally are paying more because they are not.

92% is not a fair tax rate. Nobody gets to determine how much money is too much except the person earning it.

The rich have so much money that their money makes money. Romney makes in interest in one day what I take home in one year. And most of that is now tax free for him. But don’t worry that guy flipping burgers at minimum wage now pays a greater share of his income than the richest do. That’s fair right?

Investing your money responsibly and reaping returns isn't something only the ultra-rich can do.

Again, the wealthiest folks in America pay more income tax to the Feds than any other tax bracket. If they happen to be in a situation where they can simply pay themselves a low salary to get hit by a low income tax, then get a lot of money from other ways the Fed doesn't assess, then props to them; I admire anyone who is crafty enough to take advantage of poorly thought-through code to save money.

If I were in charge, anyone with an annual gross income that's more than the Federal poverty standard would pay a 10% flat tax on said income. Then I'd throw an additional 10% on all gross corporate revenue unless it's a sole proprietorship or similar model geared only for small business. Everyone pays an equal share of their income, no business exemptions except for the types that actually need it.
