Right. Borrow $5 trillion for infrastructure and pay <$50 billion / year. That's a positive ROI for sure. Only issue is you would flood the markets and raise those rates, so you wouldn't get all of it, but still a lot. I have always though that the government should act strategically and take advantage of low rates like other market participants.

Trump runs huge deficits during boom times. He'll probably run even huger deficits during bust times.

This administration has a single minded project that has been a struggle to get financed. It would be a huge coup for them to use this downturn to get it financed without borrowing from Peter to pay Paul. Then again, this is all probably just fake news.
