If the USA has to go through civil war, revolution, collapse, etc. there's not much we can do about it. It's solely up to whether or not the people currently in the government make the right decisions to navigate the minefield that previous administrations and Congresses have left them with.
But even if those conflicts don't happen, the USA is hurting and broken pretty badly. It needs a lot of work. Structural changes to keep this from happening again and a rebuilding of various aspects, not least of all infrastructure.
There are some "advantages" to having to rebuild so extensively, from such a dilapidated system. Just ripping out the old infrastructure and putting in something entirely new and up to date will be easily justified, since the cost to resources and labor to repair the old will probably be more than just ripping it out and starting anew. That's the underlying reason why China was able to grow so rapidly, since they had no existing infrastructure to speak of really, there was no need to balance cost effective measures of repairing or updating old infrastructure. If the USA can get its shit together, we can have a major resurgence in the quality of the USA.
So there are many elements of the USA that will be on the table.
Energy infrastructure (gas, electric, nuclear, etc.).
Water infrastructure, quality, and sources.
Transportation infrastructure and mechanisms.
Public buildings (schools, maybe hospitals after this is over, courthouses, city halls, libraries, military bases, etc..)
Probably much of residential and commercial infrastructure (riots burning it down, maybe various battle collateral damage, and the inadequacies of US building regulation to handle sars-cov-2).
Food production and processing.
Manufacturing methods and the matierials used.
Currency and the legal system that regulates the economy.
The legal structure of medical treatment.
The legal structure of invention.
The legal structure of local, county, state, and federal.
Political structure (divisions of power, agencies that can be removed, fused, or separated).
Foreign policy (which countries are really our allies?).
The structure, infrastructure, and legal system of the internet (which can just be the category that all indirect communication can be categorized under).
The legal approach to new territories that may want to be completely annexed or retain autonomy.
Environmental law (nature reserves, environmental remediation, new burdens to demonstrate the degradation products of various materials and substances and their toxicity).
Domestic law (divorce, marriage, spousal rights, child support, children's rights, etc.).
Eugenics law (do we let genetically low IQ and genetically defective people reproduce their misery in another generation?).
Experimentation law (what is ethical, what requires approval, who approves it, situations where exceptions can be made).
National identity and ideology (what makes people loyal to this country).
Public welfare laws (restricting psychologically damaging or addicting things such as hard narcotics, video games, social media, gambling, porn, etc.).
Education (how it's done, what constitutes qualification in a subject, incentives).
Public welfare projects (parks, gyms, national parks, asylums, etc.).
There's a lot to think about.
What kind of country do you want to live in? Once the USA fixes its underlying instability (multi-ethnicism, tech proliferation to non-White countries, dangerous dependencies on other nations, dysgenics, and non-meritocratic control of government) and becomes trustworthy enough for more technology, it's going to get a massive cache of new tech. Once it looks like it cleared its hurdles, I'm dumping everything that looks like it would be useful and offering support to technical problems, and I expect others will do the same.
