It's April 16th, and every American has just had to hand over stacks of cash to Uncle Sam.

Wait, that's right, not EVERY American. Nearly half don't pay a cent in taxes, and that's starting to irk those who do pay.

Twenty-three percent of those surveyed by Gallup said they think the "lower-income people" pay too little in taxes. That number stood at just 12 percent throughout much of the 2000s, but has been on the rise since 2010, when the GOP took over Congress. By 2012, when Republican Mitt Romney made the disparity an issue in the presidential election, the number hits its modern record of 24 percent.

There's no doubt many people earn too little to afford the federal government's steep taxes; others have families, and still others are disabled or elderly and not working anymore. The "progressive" tax system was designed to protect those people, but many Americans now feel that plenty are abusing the system (the ranks of those on "disability" have doubled since President Obama took office).

Meanwhile, the Gallup poll showed a new record in the percentage of people who think the middle class pays too much in taxes. Forty-nine percent said taxes are too high, up from 36 percent in 2012 (and who is that 7 percent that said the middle class pays "too little").

The number who thought the middle class paid its "fair share" had been stable for some time, rising to 56 percent as Obama demagogued the income equality issue. But that's changed as the economy stays in the doldrums for the fifth straight year.

Another study, this one by the Tax Foundation, found that Americans will spend more in taxes than they do on housing, food and clothing. That's right: They're going to fork over some $4.5 trillion -- with a "T" -- to the federal and local governments, but spend just $4 trillion on themselves.

Republicans prepping for the 2014 mid-terms are apparently aware of the rising distaste among Americans. They celebrated Tax Day by suing the Internal Revenue Service, claiming that Team Obama withheld documents sought in a Freedom of Information Act request over whether the IRS targeted conservative political organizations.

"We’re filing this suit because the Obama administration has a responsibility to be transparent and accountable to the American people. The IRS has a legal obligation to answer our inquiry for these records," RNC Chairman Reince Priebus said in a statement.

"On Tax Day especially, Americans deserve to know whether they can trust the agency to which they’re sending their taxes."
