Dude, com'on. This argument is so silly. If the government can get a better value for their money from buying from foreign firms, why would we want them paying more for "American" made products? Proponents of government spending should take special care to insure that government tax dollars are used as efficiently as possible...
Two very easy points that debunk this line of argument:
1. I've cited Businessweek's cover story a few times, and I'll cite it again just in case you haven't read it. When our government spends money in the country, it creates an economic ripple effect/multiplier effect in our country, even if the price of a given domestic-made good is higher. Say we pay an astronomical 30% higher for a good made in the United States. Well, that money pays someone a wage, and that wage is pretty likely to get spent in the country. That wage is also taxed, which means the government recoups some of the revenue. Now, let's say we pay 30% less for a good made in China. We may save a little money, but the money we've spent just left the country with no ripple effect whatsoever. As Businessweek shows, if we allow that kind of "leakage" in stimulus spending, we'll likely undermine the stimulus package's effectiveness.
2. I've said it before, and again - I'll say it again: The Buy America laws include specific provisions allowing the President to waive them if the price of the goods in question are more than 25% more expensive in the United States than on the international market. So even if you subscribe to the right-wing/ignorant argument against Buy American laws based on higher prices, there is a safety valve to address your concerns.
The one thing Max Berger has right is that "proponents of government spending should take special care to insure that government tax dollars are used as efficiently as possible." Indeed they should - and a basic, grade-school level understanding of economics shows that the way to do that is to support Buy America laws.
