I supported QEII under the 'do anything' view, but it's probably the case that it's short term impact was making rich assholes richer with perhaps a few pennies shaking free from the wallets and landing on the rest of us.
A stock market crash is about the only thing which will make elites act, though they will act to... make sure rich assholes remain rich. Any positive impact on the rest of us will be chance.
