None of these are truly new - even the quarter-baked coup attempt (see FDR times.) As for outrageous debt, that began with the US itself.

Which raises the possibility that we're looking at the nasty part of a regular oscillation.

However. The very low birthrate is genuinely new. Drugs/homelessness not new but astonishingly severe. Steep housing prices due to collusion (vs manufactured homes, housing laws, and more) are a large cause of both.
