It now looks like half of President-elect Barack Obama's stimulus package will take the form of "tax cuts" for 95 percent of all Americans. Yet this wouldn't so much boost the economy as trigger a massive, unhealthy shift in American politics.

Under Obama's plan, the majority of American voters would pay no federal income taxes, but would get money from the government instead. That is, these "refundable tax credits" are basically welfare checks - and Obama's plan would leave the most of us collecting, not paying.

A $200 billion giveaway won't do much to get a $14 trillion economy rolling again. But the plan would leave any future taxpayer revolt no hope of majority support.

Today, the bottom 50 percent of US taxpayers pays a total of $30.6 billion in federal income taxes on a combined income of about $1 trillion. So about 3 percent of all federal income-tax payments come from the poorest half of the country. (The top 1 percent pays 40 percent; the top 25 percent pay 85 percent of the federal income tax.)

Obama's plan - he'd give all couples a $1,000 refundable tax credit and all single people $500 - would funnel more than $50 billion to the lowest half of the country, thereby completely wiping out their total federal tax liability. In most cases, it would trigger a "refund" welfare check.

In one stroke, this would transform the majority of voters from taxpayers into tax eaters - and leave an increasingly small minority to pay the bill. Whether or not this is good economics, it is very dangerous politics.

Essentially, it would put those who actually pay the taxes that fund our government into much the same situation as landlords in New York City - hopelessly outvoted by their tenants, who use their political clout to limit rents and landlords' profits. Continued...
