I don't know anything about economics. My thoughts keep gravitating towards the US and Canada employing people to invest in infrastructure upgrades. It's a way to address a serious concern in both countries (especially the US), put cash into the hands of citizens, thus the economy, and give a lot of people a bit of hope.

You wouldn't need to create tens of millions of jobs directly in infrastructure, just enough that the money would move around and make related business possible.

Maybe this is a really stupid idea, I don't know.
