the staggering vastly-underestimated burden of payroll taxes and the evil of tax withholding

From Charles Murray in WSJ...

First, he focuses on the so-called "income tax":

We have the worst of both worlds. The rhetoric of the president tells the public that the rich are not paying their fair share, undermining the common understanding from the bottom up. Meanwhile, the IRS recently released new numbers on who pays how much taxes, and those numbers tell the people at the top that they're being exploited.

Let's start with the rich, whom I define as families in the top 1% of income among those who filed tax returns. In 2007, the year with the most recent tax data, they had family incomes of $410,000 or more. They paid 40% of all the personal income taxes collected

Yes, you read it right: 1% of American families paid 40% of America's personal taxes.

The families in the rest of the top 5% had family incomes of $160,000 to $410,000. They paid another 20% of total personal income taxes. Now we're up to three out of every five dollars in personal taxes paid by just five out of every 100 American families.

Turn to the bottom three-quarters of the families who filed income tax returns in 2007—not just low-income families, but everybody with family incomes below $66,500. That 75% of families paid just 13% of all personal income taxes. Scott Hodge of the Tax Foundation has recast these numbers in terms of a single, stunning statistic: The top 1% of American households pay more in federal taxes than the bottom 95% combined

My point is not that the rich are being bled dry. The taxes paid by families in the top 1% amounted to 22% of their adjusted gross income, not a confiscatory rate. The issue is that it is inherently problematic to have a democracy in which a third of filers pay no personal income tax at all (another datum from the IRS)...This deforms the behavior of everyone—the voters who think they aren't paying for Congress's latest bright idea, the politicians who know that promising new programs will always be a winning political strategy with the majority of taxpayers who don't think they have to pay for them, and the wealthy who know that the only way to get politicians to refrain from that strategy is to buy them off.

Then, to the biggie: payroll taxes on income-- and how they can be part of the solution:

...make an accounting change, no longer pretending that payroll taxes are sequestered in trust funds.

Fold payroll taxes into the personal tax code, adjusting the rules so that everyone still pays the same total, but the tax bill shows up on the 1040. Doing so will tell everyone the truth: Their payroll taxes are being used to pay whatever bills the federal government brings upon itself, among which are the costs of Social Security and Medicare.

The finishing touch is to make sure that people understand how much they are paying, which is presently obscured by withholding at the workplace. End withholding, and require everybody to do what millions of Americans already do: write checks for estimated taxes four times a year.

Both of those simple changes scare politicians....
