I'll add: if a central bank didn't pay its government the interest it received on the bonds it bought with quantitative easing, but instead cancelled 1/4 of it, and lowered the price it will sell the bonds by 1/8 of what it received in interest, using the rest to invest in it's own country's stock market, to build sovereign wealth funds:

Funding students in tertiary education (so the smartest get in, not 'dumb rich kids'),
Funding roads,
Funding independent schools,
Funding health care,
Funding old age pensions,
Funding nursing homes, and,
Funding the armed forces.

That would change the country for the better. Enough new money was stupidly dumped into the systems for this to be possible.

Also, when the bonds are finally sold, the money is cancelled up to the quantitative easing funds (bond for bond), and the profit paid to government, who can pay down their massive debt with it, as the generations after the baby boomers will struggle to do that for a long time - the only way out I can see. That list therefore may not be completed, but it doesn't matter, solving, even partly, the problems the next generation are about to inherit does.
