Okay, several problems. In no particular order:
I actually agree with all your points, but I'm going to play devil's advocate for the moment.
* Money is fungible; just because I can't spend this $100 on anything but clothes doesn't mean that I will spend $100 more on clothes.
Let's consider three types of citizen. First, there are the good people of America who are out stimulating the economy at a breakneck pace every day. This plan won't affect them, except maybe some minor inconvenience. They're already spending their money.
Then there are the people who could be spending money, but aren't. These miscreants are making more than the minimum payments on their credit cards every single month. Some of them, astonishing as it may seem, have no debt at all, and they could be buying a Grande at Starbucks dressed in their brand new shoes, but are opening savings accounts! It is this class of non-consuming consumer that the Stupid Stimulus Plan is aimed at.
Finally, there are people who just can't pay their bills anyway. This plan will force them into bankruptcy, at which point those bills will be wiped away. In the meantime, they'll at least buy some stuff, and that creates jobs. And those jobs give paychecks to workers, who will buy stuff, and create more jobs.
So, your point is correct, but the Stupid Stimulus Plan will increase demand, just not on a dollar for dollar level.
* It would be quite expensive to carry out (cards and postage aren't free); while spending money is a goal of the stimulus plan, that doesn't mean it should be done stupidly.
True, but not much more expensive than the other stimulus plans.
in a way that creates long-term jobs and longer-term infrastructure. Spending $100,000 to create or repair a bridge means that you now have a bridge you didn't before,
Let me come back to this one in a minute.
The money behind the stimulus cards would still have to come from somewhere (i.e. long-term debt).
True, but it wouldn't increase national debt. The money would come from the paychecks. Basically, the Stupid Stimulus Plan is a way of requiring people to spend money on unnecessary goods which they might be otherwise inclined to save or use to pay down debt.
OK. Enough Devil's advocate for the moment. In truth, I think that the real problem with the Stupid Stimulus Plan starts with your first point, but your first point doesn't go far enough. Money is indeed fungible, which means moving it from one place to another doesn't matter. The Bush stimulus plan didn't work because it moved money from here to there. (Treasury to taxpayers) However, since the Treasury was spending more than we were taking in, that fungible money was pulled from somewhere else. No real gain.
The Obama plan is only slightly better, and only maybe slightly better. It still moves a bunch of money from here to there, pulling it out of the economy in one place and injecting it into someplace else. The one advantage it has is due to that point I said I would get back to. At least with the Obama plan, we get a bridge. Assuming we need a bridge, that's a good thing. It takes idle people and gets them working. To the extent that they are doing something of value, it stimulates the economy, by making things we actually want.
Building a Bridge to Nowhere would employ just as many people, and move just as much money from here to there, as building a useful bridge, but at the end of the project, one of them creates a bridge.
The real problem with the Stupid Stimulus Plan is its premise. Its premise is that if only people would start spending, and borrowing, money, everything would be ok. The premise is that the problem is lack of demand. I don;t think that's it. I think there's plenty of demand. The real problem is that we are in debt up to our ears. Our national debt is staggering, and our personal debts are staggering. Finally, those bills are coming due, and we can't afford to buy more stuff.
The Stupid Stimulus Plan has the same problem that the Bush plan had. It pretended that the economy would take off if only we moved money from here to there. It pretended that the problem with the economy was that people just weren't spending enough money. That wasn't it, and it failed. The Obama plan has some virtue in that it is spending money on things that are worthwhile, but its benefits, I think, are overrated. That's because money is fungible, and that money has to come from somewhere, and whereever it came from, it could have been spent on stuff other than bridges. So, if any of it is spent on stuff that no one wants, that portion is a total waste.
That's enough for the moment.
