I would:
1) Temporarily lower full benefit retirement age to 62, and partial benefit to 60.
2) Medicare eligibility to 60, Medicare buy-in at 55 (individuals or businesses employing them).
3) Allow primary residential mortgages in bankruptcy.
And there would be much rejoicing throughout the land.
If we need to figure out how to pay for this stuff, a modest transaction tax on financial asset trades would be a start.
