Massive disparities between rich and everyone else is a symptom of an unhealthy society. That goes for feudal serfs and kings or hungry people in the streets while the rich live in opulence. It's an insurmountable distance and is actively maintained by those with power.
I just don't see that here in the US.
In fact from what I see everyone in the US, pretty much, has access to a hot shower in the morning, breakfast and access to a public school education.
This is just for starters but with the availability of help buying food I don't see too many people being hungry. In fact It's my opinion that too much food is an issue in the US. And from what I hear the US is the second most obese nation on the planet.
As far as those in power maintaining any "insurmountable distance" I think that you'll find that Bill Gates has donated BILLIONS of dollars to poor people to give them a big boost in education. Many other wealthy people have donated much of their assets to helping other get ahead.
I've never seen a case of any rich person attempting to keep any poor person down. My observation is that's it's the other around. Like the example I mentioned along with generous people like Mark Zuckerberg the exact opposite is what I've noticed.
But that's just me.
