"Ryandian" economics the new snake oil. Rep. Paul Ryan actually believes small business tax myth IRS says isn't true.

Undeterred, Rep. Paul Ryan won't let a favorite untrue talking point go unused, over and over and over...

From PolitiFact: 

Of all taxpayers who declare business income, about 2 percent declare enough income to see tax increases if the rates on the top brackets expire. Most small business owners would not see a tax increase, though the most profitable small businesses would.

Republicans often say they're opposed to the tax increases because they will hit small businesses, but the numbers don't really support that … most small businesses aren't nearly that profitable. In fact, Internal Revenue Service data shows that of all taxpayers who declare business income, only 2 to 3 percent declare that much. We rated this Pants on Fire.  

(It’s also) wrong because gross sales are all the money a business takes in. Under longstanding IRS rules, businesses get to deduct most expenses before reporting their final taxable income. That includes things like employees' pay, supplies, a car or truck, fuel costs, advertising, and more. 

This tax truth should be thrown into the discussion:

The United States of America is overtaxed "compared to our competitors." The Organization for Economic Cooperation and Development compiles data on how much government’s tax; they measure it as the proportion of tax revenues compared to the size of the economy. In those terms, the United States is fairly competitive in terms of overall tax burden, with revenues of 28 percent of gross domestic product in 2007. That's lower than the average of 36 percent among 30 major countries. Only South Korea, Mexico and Turkey were lower than the United States.

Keep in mind, those other major countries also include universal health care in their governments tax bills.
