I think we are effectively already in a dictatorship

Brink?

I don't think it's that oligarchs want the US society to collapse, it's more that they're seen as reckless in their pursuit of getting that seat at the table of those in power. They're probably smart enough to know that eventually this path will lead to someone's destruction, but they're either confident or arrogant in their belief they'll be unaffected. Only time tell which it is

The system isnt rational, if something is good for business and good for workers, then it is a threat to the oligarchy. This is why a class analysis is so important.

During covid, wages went up, unemployment went down, profitability soared, business was pretty good in many sectors. What was the response? Raise interest rates, increase unemployment, drive down wages, increase prices.

Once you realise that unemployment and inflation are really one metric, it demonstrates how imprisoned the "free market" actually is. Good for business means little, only a society where workers own their time and produce is capable of being rational and fair

There's a level of wealth at which wealth loses meaning. Not in the "all things cost what I consider pocket change" sense, but in the "I'm so wealthy no one charges me money anymore" sense.
What matters then is consolidating that position, and establishing power, as opposed to wealth. It doesn't matter if the economy tanks if your position isn't based on economics. If the anarchy in question is people no longer listening to rules, that's a great time to put yourself in a powerful position that the rules say shouldn't exist. From that perspective, destabilization is just them pushing stuff they don't care about out of the way.
