This is why I'm not really a big fan of stimulus incentives that essentially hand out money for people to spend - i.e. stimulate consumption.
What we need to stimulate is innovation + production (better, quicker, faster, cleaner ways to doing things).
N.B. Stimulating consumption isn't necessarily a terrible idea when it has a downstream impact on production. In fact, this lets the market drive innovation, which historically has been a good idea.
The problem is the credit environment really screwed with this -- "Wealth" was appearing that wasn't tied to some genuine increase in production. Usually this works. Extend some credit, someone builds something new/cool and we've created wealth. It doesn't work when it just leads to increased leverage.
.. And so this vanished, because it wasn't really there.
Everything has a cycle + I think it's time to turn away from stocking the consumption boiler and boost grass-roots innovation.
