There is a word for this sort of viewpoint: Luddite fallacy ( http://en.wikipedia.org/wiki/Luddite_fallacy ) It amazes me how people fail to see their own Luddite-ism. Look, here's the deal: The Luddites protested the mechanization of the textile industry during the industrial revolution. Their reasoning was that if one person maintaining one machine could do the same work as 100 individual laborers, then that would…
Now it is certainly true that we'll be in less trouble if the economy grows faster than the hole being dug, but a hole is still being dug. If things improve it would be in spite of, not because of, the indebtedness being incurred. Again, the luddite fallacy is not applicable.
It is also certainly true (and proven over the centuries) that investment of capital accumulated through deferred consumption can, when applied toward improvements in technology, yield productivity gains, thereby improving the balance sheet of the inventor and the living standards of the common man. Such gains will emerge from the market, revealing what works and what doesn't, and in not working will free that capital to be put to more productive ends. It's not at all clear to me that a debt-funded, politically-allocated system will yield better outcomes.
