> I don't see anyone mentioning that the United States needs to manage its massive national debt, currently in the trillions, by issuing Treasury securities.

It's very hard to even assume that's a concern of the current US administration, based on not only the fundamentalist goal of radically cutting taxes and regulations, coupled with the fact that it's purposely pushing a recessive economic policy that defies any logic or reason.

The very least that you'd expect is a progressive tax policy that didn't excluded corporations and mega-rich. You're not seeing any of that.
