It's good, if you work for the automobile manufacturing industry. It's good if you're in a position to take advantage of the government handout to help buy a new car, when you otherwise could only have afforded to buy a used car. Some people did benefit from this scam. Nobody's denying this.
But the vast majority of people did not benefit. Those who benefitted did so at the expense of all of us who had to pay for it through taxes. Most of us had to pay taxes to support this scam, and got absolutely no benefit whatsoever in return.
Further, those of us who were in the market to buy a used car, but not in a position to be able to afford to buy a new car even with the help of this scam, were further harmed, because the supply of used cars has been diminished, and their price, as a result, increased.
If Big Brother were to take a thousand dollars in taxes from one person, and give a thousand dollars in handouts to another, you could say that the net effect was neutral; one person gained exactly as much as someone else lost. That is not the case here. Government spent billions of dollars to buy up valuable cars, at prices above their market value, just to destroy them. Those who previously owned those cars gained. Those in the business of manufacturing and selling new cars to replace those that were destroyed gained.
Everyone else lost. And because wealth was directly, deliberately destroyed, in the process of redistributing it, those who gained gained less than was lost by those who lost. This is less than a zero-sum game. On the whole, this left us, as a nation, poorer by the value of all the cars that were destroyed.
Instead of being like my earlier example, of government taking a thousand dollars from one person in taxes, and giving a thousand dollars to another as a handout, this is more like government taking a thousand dollars from someone in taxes, throwing five hundred dollars of it on to a bonfire, and then giving the other five hundred to someone as a handout.
