Tax cuts enacted in the past decade have been generous to wealthy taxpayers, too, making them a target for President Barack Obama and Democrats in Congress. Less noticed were tax cuts for low- and middle-income families, which were expanded when Obama signed the massive economic recovery package last year.

The result is a tax system that exempts almost half the country from paying for programs that benefit everyone, including national defense, public safety, infrastructure and education. It is a system in which the top 10 percent of earners -- households making an average of $366,400 in 2006 -- paid about 73 percent of the income taxes collected by the federal government.

The bottom 40 percent, on average, make a profit from the federal income tax, meaning they get more money in tax credits than they would otherwise owe in taxes. For those people, the government sends them a payment.

"We have 50 percent of people who are getting something for nothing," said Curtis Dubay, senior tax policy analyst at the Heritage Foundation.

(All emphasis mine.) Man, it must be nice to get stuff for free, with the burden of actually paying for things shouldered by others. And they all get to vote, too; I wonder, do people who get free stuff vote for more free stuff? And when they outnumber the people who have to pay, what then?
