U.S. perspective here:
We're talking about a country where the national philosophy of life is consumerism, and where people happily sacrifice years of their life, endure terrible inconveniences, consume unhealthy food/water/air, allow much of the population to live in poverty, run a risk of not being able to afford lifesaving medical treatments, and buy utterly unnecessary things for the excitement of buying it.
We do so because these sacrifices are believed necessary to keep the money flowing into stocks, real estate, and "job creation". The elderly, the mentally ill, disabled people, and addicts can be seen begging on the streets, and our taxpayers won't help them because they are non-productive economic assets. People routinely die here so that we can maximize GDP. We are now re-legalizing child labor to squeeze a bit more profit out of people who are otherwise liabilities. We are taking away access to government-provided healthcare for millions because we know tax cuts spur economic growth, and because we want to incentivize the poorest people to work harder and produce more.
This is not a country at risk of some kind of communist seizure of all assets. Property rights are paramount. In Star Trek terms, we are the Ferengi. We will happily give up all our freedoms if we can be persuaded there is a profit to be made. But numbers in an account are scripture.
Other cultures compromise on the value of accumulating property and income, and also make policies on humanitarian, traditional, or pragmatic quality of life values. Not the modern U.S. We have only one value, and that is money. We will sacrifice tradition, family, freedom, dignity, pride, safety, our own health, and the lives of our fellow citizens for the sake of stock prices and growth statistics.
Does this eventually lead to totalitarianism? A return to serfdom or slavery for the people whose ancestors once escaped such conditions? Yes it does. But in the meantime it's a great place to be invested because the whole nation is oriented toward this one ultra-primary value of accumulating economic assets. Any politician who endangers that goal will lose the next election. Asset seizures are inconsistent with the national objective.
That said, I think the bigger concern is that the U.S. could destabilize is destabilizing itself by being so single-minded. Everybody is dissatisfied here. Most think it is somebody else's fault (rich people or minorities, depending on political affiliation). Almost nobody understands the bigger picture, that we are optimizing one aspect of life at the expense of everything else. So we have a pattern of desperately falling for political gimmicks, such as tax cuts that increase the deficit, or subsidies, or free college, or stimulus checks from the treasury, or whatever. We're all in favor of dismantling many of the institutions that brought such great success in the past. Eventually we will reach the ultimate gimmick, which involves granting total power to a CEO-emperor, who promises to make everyone rich.
I suggest you stay diversified, and I am working on diversifying too. Understand the alternatives involve investing in cultures that are not 100% committed to money-making, and so long-term returns must be lower. You might even invest in the eventual victims of whatever nightmare the U.S. becomes. Ancient Rome enslaved entire populations despite its utter corruption, so keep an open mind to the risks and possibilities.
