If Biden takes office, things will quickly return to "normal". I say this because that is Biden's whole brand. Its at the core of what he is offering. "Vote this corrupt, incompetent madman out so this madness can end and things can go back to normal"... And in the current political, social, and economic climate, that is exactly what so many are desperate for.
See my above comment about Biden. What I expect Biden will do... what Presidents usually do... is just let the system run itself via the various departments and appointees that have been put in place, either by them, or by previous Presidents. The country does, figuratively speaking, run itself, in the sense that there are so many people, working in different levels of government, institutions, agencies, departments etc., with so many systems and rules and procedures and traditions in place... but here's the catch... this only works if you don't screw around with it too much and/or actively destroy and/or obstruct the functioning of the system.
Its like the plumbing in your house. It just works for the most part, with occasional very specific/targeted maintenance. Trump comes in and says... "I don't like all these brown pipes, I'd rather have white ones!" Then he rips out all the copper plumbing in the basement and sticks pcv pipes in the places that he remembers seeing copper pipes, without any knowledge whatsoever of what he is doing, what types/gauges/shapes of pipe go where, where all the connections were, how to create seals in the fitting joints, etc. So then of course when you turn the water back on, its a total disaster, water/sewage everywhere and nothing works. Then he blames "the Democrats". See my above comments. The systems pretty much run themselves as long as the people in charge don't screw things up too much.
