I don't know who feeds him his ideas, but he lacks experience, judgment, and wisdom to fully evaluate them himself, and is at best an unskilled popularizer of spurious memes. The few times he says something not totally sophomoric, it's almost certainly due to random chance alone. Broken clock is right twice a day.
If you're going to listen to any one person on this issue, Andy Grove is the one:

Invention is not a necessary or sufficient condition for prosperity. You can arrive there via many paths (thriftiness or wise investment, service provision, etc.).
"We cannot bail or tax-cut our way to prosperity. We can only, as Jobs understood, invent our way there."
Measuring GDP, inflation, deflation, the unemployment rate, all of these numbers are not a reflection of quality of life. Prosperity is a quality of life issue which is solely improved (or destroyed) through technological advancement.
