Here's the sobering answer from ATR president Grover Norquist: Through dramatically higher taxes. From his piece on NRO:

Thanks to the Bush-Obama-Pelosi-Reid “stimulus/bailout/pork/omnibus” bills, federal spending alone this year will be about 30 percent of GDP, according to Strategas LLP. That’s the highest level since 1945, when World War II was drawing to a close. Since then, the average has been only 20 percent of GDP, a figure that held up as recently as two years ago. Yes, since 2007, the federal government has managed to increase spending by 50 percent. And eventually, if spending is not curtailed, there will be pressure from the mainstream media and Democrats to raise taxes to “address the deficit” caused by all this new government spending.

Taxpayers, of course, are accustomed to hearing from official Washington how taxes may have to go up in the distant future to pay for the unfunded obligations of Social Security, Medicare, and Medicaid. This is a looming threat, and it makes the above numbers all the more ominous. The bailout and stimulus-spending bills will have to be “paid for” in the minds of the media and the Obama-Pelosi-Reid regime with higher taxes.

Frighteningly, a multi-trillion-dollar tax hike is already baked into the cake. On Jan. 1, 2011, just a shade over 22 months from now, several rates are scheduled to rise: The tax rate on most small-business profits will elevate from 37.9 percent to 42.5 percent. Also increasing will be the nest-egg taxes on capital gains (15 to 20 percent) and dividends (15 to 39.6 percent). And the death tax, which is set to die in a mere ten months, will come roaring back at a 55 percent rate on estates valued over $1 million.

Unfortunately this is just the tip of the iceberg. Click here if you can stomach more.
