Ask Joe Biden ....economic numbers were awesome. Yet people felt things sucked why? Because outside of the Whole Foods caste - the top 20% ---things SUCK ROYALLY.

The middle class is contracting. There are numerous reasons for this, including enabling the rich to get richer at the expense of the not-rich. Also, the RW media spent most of its time blaring that things were horrible (and then -miracle!- the Felon is elected and everything is A-OK).

Modern family structures,...

Not sure it's governments business to try to dictate that in any way. The Reps are big on trying ("family values!"). I think the Dems have a more realistic grasp (and acceptance) of how that is evolving. And evolve it will, whether we like it or not. Fewer marriages, fewer babies (our birthrate is under replacement levels, last I knew).

When in fact, the structural, some self inflicted things that SUCK for people out there....will suck regardless of what party is in power.

Probably. The self-inflicted thing is hard to resolve. Things suck less when Dems are in control (at least since Reagan), at least domestically. Deficits get reduced, on occasion something good happens (like the ACA...for all its flaws, it's better than what we had; also the CFPB). International is harder because we can't control Putin or Kim or Xi. We just have to deal with them as best we can.
