Government spending is inherently wasteful because they do not make economic decisions based upon profit or loss. There is no feedback signal like private businesses have. Governments also tend to have centralized decision-making bureaucracies, which cannot make important decisions as quickly as a decentralized system of millions of people acting in their own self-interest. (Not that private companies are totally immune to this; excessive bureaucracy has been the downfall of many big companies, but at least they are punished by the market unlike government) Finally, governments make economic decisions based on what will get politicians the most votes, rather than on hard economic reality. If government could make the correct economic decisions, then centrally planned socialism would work.
A few other points:
* Government statistics should
always be taken with a grain of salt. The feds have repeatedly changed the way inflation and unemployment are measured for example. If we were measuring things the way we did a few decades ago, inflation would be around 8% now, and unemployment would probably be somewhere around 12%. This isn't something new or unique to the Bush administration of course.
The problem has become bad enough that economist John Williams actually runs a subscription-based website which gives adjusted numbers for inflation, GDP, monetary expansion, unemployment, etc.

* Tax cuts are good because a smaller government leaves more money in the hands of the free market. The key point here is smaller government though, and the
real number to look at isn't tax rates, it's
government % share of the economy. Let's say we cut taxes but maintain or increase spending. The resources that the government is hogging have to come from
somewhere. And that "somewhere" is currently borrowing and money printing.
So we haven't really reduced the heavy yoke of government; we've just shifted it around. Looking at inflation, well it's basically a stealth flat tax. And we were running the printing presses (so to speak) red hot from 2001-2005. (Note: the banks are given the priviledge of creating the bulk of the money supply, coordinated by the fed. Thus we see a tidal wave of cheap money which lead to the housing boom, which has taken a nose dive in recent months and will create a spectacular crash in the months ahead) In fact the fed had to quit reporting the M3 money supply statistics. (Supposedly this is to cut costs--ha! From an organization that creates it's budget out of thin air.)
Then you've got borrowing. "But Baron, borrowing isn't necessarily bad; as long as we have a big strong economy in the future to pay for it!". Well, no. When the government borrows money, it isn't hopping into Doc Brown's time traveling DeLorean to travel into the year 2036, when we're all richer and can more easily afford to pay 2006's tax bills. No, the money the government soaks up via bonds represents resources that could have gone towards say...corporate bonds. Or whatever alternative investment people would have chosen in the private economy. The steel, gasoline, labor, etc. gobbled up by leviathan could have stayed in private hands and improved our standard of living.
Anyway, this should not be taken as a swipe at republicans specifically; democrats have proven themselves bad too. I am not arguing one party or another, I am arguing bad policy vs. good policy, regardless of who's in charge.

Jude Waninski was a fan of tax cuts, but even he pointed out that some tax cuts are better than others at producing a supply-side effect. Namely, taxes that punish capital formation (capital gains tax) are the worst and should be cut to zero. In his book "The Way The World Works", he also points out that just looking at simple tax rates can be deceptive. Japan may appear to have high taxes, but they also have loopholes big enough to drive a truck through.
Unfortunately he mostly overlooked the role of inflation and borrowing as stealth taxes. Although in his defense, inflation would not be nearly as big of an issue under his ideal monetary system, a sort of quasi-gold standard similar to Bretton Woods.
