Debt to GDP to me is a dumb metric, but wow that bad boy is climbing.

Debt to income is a better metric, much like a person. Most Americans have a large mortgage, their debt to net income is pretty damn high, more than 100% as well. Maybe 400k in debt to equity and savings of 200k. 200%. However, the debt to income is the crucial factor there, how much is their mortgage and other payments to their income.
