That's good for society. I doubt that many of the moderately wealthy would really be a cause of this. It seems the ultrawealthy are the main cause in the downfall of empires, as they hold the most influence and become leeches off the people working. And now we democratize those negative decisions via things like REITs, so everyone's 401k is part of the problem.
Historically, the decline of most late-stage empires was triggered by spiraling economic bifurcation.
Sometimes, it's better to be less wealthy but on top of an ordered country vs more wealthy and without the rule of law as society breaks down.
