I work for the DoD and when the Department of Homeland Security was established,we helped them with many things, not the least of which was contracting. To make a long story short, you cannot juice up a government agency's budget by tens of billions (or in the case of the stimulus package, hundreds of billions) and expect them to be able to process the paperwork to contract it out, much less oversee the projects or even choose them with any kind of hope for success. It's like trying to feed a Pomeranian a 25 lb turkey. It's madness.In short, you can argue about what sort of stimulus spending is best, but in the end it is going to be nearly impossible for the Obama administration to ramp up government spending by any significant fraction next year. It would probably take at least several years before any meaningful increase in spending on infrastructure and alternative energy projects actually occurs. Government already spends a gargantuan sum of our money, but the logistics of spending even more of it are incredibly complicated and time-consuming.
Two thoughts flow from this: 1) perhaps Obama doesn't really care about stimulating the economy, and is simply using the current crisis as cover for promoting a massive environmental and union-friendly agenda, and/or 2) as his team drills down to the specifics of what they are proposing, they will realize that since stimulus by government spending is extremely difficult and time-consuming, it would be best to kick things off with something that has a high probability of success and can be implemented very quickly: tax cuts.
