Look around the world, and put all the countries that are running deficits in a column. Put their revenue as a percentage of GDP in another.
Now do the same with the countries that are not running deficits.
Then tell me if there is a correlation between the size of the deficits and the amount of revenue they collect. You’ll find that that there is none. Some of the countries that collect the most in revenue also run the biggest deficits.
Whether a country has a deficit or not is almost entirely determined by their spending habits, not how much money they haul in.
In fact, look at these historical Budget Tables. You tell me if there’s a correlation to be found anywhere in there between amount of revenue collected and the size of the deficit.
For example, in 1968 the government had revenues of 153 billion, and a deficit of 27.7 billion. By 1982, revenue was 617 billion, but the deficit was 120 billion. By 1990, revenue was 1.03 trillion, and the deficit was 217 billion. In 2002, revenue was 1.85 trillion, and the deficit was 317 billion.
Now explain to me how raising taxes will make the deficit go away. These numbers support my assertion that government will tend to spend all the money it collects, plus as much more as is politically palatable. When the cold war ended, politicians weren’t talking about cutting the size of government - they were talking about how to spend the ‘peace dividend’.
If taxes were raised 20% tomorrow, I would expect the deficit to decline in the next year. Then, as the political pressure dropped away from deficit spending, it would climb again to the point where the public opposed further deficit spending. The long-term result of the tax increase would be NO change in the deficit, but a bigger government.
On the other hand, if Bush’s tax cut is passed, I would expect to see a short-term hike in the deficit. But this would put pressure on the government to spend less, and the result would be a longer-term reduction in spending. The end result would be a smaller government, running deficits about the same size as a percentage of revenue.
Again: deficits are not determined by how much money a government brings in. Deficits are determined by how much tolerance for borrowing the voting population has. A magical money pig could fly down tomorrow and double the government’s revenue, and in ten years we’ll still have deficits - but a much bigger government.
