Seventh, programs such as Cash-for-Clunkers have no regard for lower-income consumers. By mandating the destruction of trade-ins, Congress removed 700,000 cars from the used-car market, inevitably driving up prices of the cars that lower-income consumers tend to buy.
And by ordering that a trade-in’s engine be destroyed by replacing its engine oil with a sodium silicate solution (which turns out to be in short supply!), Congress sharply reduced the salvageable used parts that are bought mostly by poorer consumers to keep their cars running.
There’s more, but you get the idea.
