Systemically, how would you solve homelessness, if I gave you a trillion dollars?

A trillion in a money market fund @ 5% is 50B/year.

Over the course of a few years (so as to not drive up the price of politicians too quickly) one could buy the top N politicians from most countries. From there on out your options are many.

After a decade or so you can probably have your trillion back.
