Prosperity is generated by production not consumption. And who's most likely to invest in improving productivity?
I don't worry about stimulating demand when bubbles collapse. The viable parts of the economy get to pay lower prices for everything. That stimulates ORGANIC recovery and growth and avoids re-inflating the bubble in the fake parts of the economy that will only re-collapse again.
Delaying the collapse of unsustainable pricing and investment in non-viable sectors only makes their collapse bigger and more wasteful.
