There is something wrong with this economy if it crashes because I and millions like me choose not purchase unneeded and unwanted goods and services.
I suspect it has to do with the unbelievable pace of the modern economy. Choices to produce, ship and offer for sale a good or service are little more than guesses about which particular ones will be successful. These items are produced and marketed so quickly these days....well, guess wrong and you're burdened with non-performing overhead costs, stuck with unsold inventory and your mailbox or inbox is full of due bills and host of fed/state/local taxes.
Whereas a hundred or more years ago, my decision to wait another year or two before I buy that icebox or radio was allowed for in the business model of Sears or the local merchant.
Weird. People complain saying Americans don't save enough, and then they complain saying Americans save too much.
