Taking on debt so that the .01%ers can avoid paying taxes is a completely different situation than investing in infrastructure so that jobs and economic activity gets dispersed. Paradox of thrift is still a valid concept. Take a yuuuge mortgage to flip a house is different that someone buying a house to live in. House flippers don't need washing machines and furnishings- which generate secondary spending. And no, this is not trickle down economics. That is a different thing.

We had the business leaders running the US Treasury for too long. It didn't end well for the average family or middle class worker. Watch the "big short" or "Capitalism not a love story".  Rich simple got richer. 

If you are going to incur debt to increase GDP, put it in the hands of people who will spend all of it within local economies on tangible goods and services.
