Yes, and it created an actual problem that (knowingly or not) Trump was responding to - America essentially was getting further and further in debt to enable such high consumption.
I think we'll find that quite a bit of "American Exceptionalism" has been low interest borrowing. I'm not sure to what level, but I think anyone who relies on the S&P 500 as their only investment is going to be disappointed in the future decades of returns.
The futures graph for S&P looks real close to the national debt graph, and both look like they're at peak bubble.
Probably doesn't mean anything.
