I think the "doing vs. owning" paradigm explains pretty well how human societies operate.
What seems almost inevitable is the fact people gaining wealth through doing eventually switch to the "owning" mode due to their wealth having reached a level enough for that. It's like the path of least resistance. What follows is that whatever a society is composed of, it always tends to the wealth getting concentrated in a few owning hands.
Things can turn around when some kind of "revolution" happens, but then the cycle will just repeat.
Well, that is one purpose of property taxes, and the principal one IMHO. It does not matter how much you own, if the state taxes property at 2.5% then in 40 years it's taken it all. So If you have property and want to keep it then you better make sure it is earning you more than what you pay in taxes and that way the property is generating wealth and economic activity.
There are many rich families who in few generations lost it all and there are many people who started out from nothing and became rich.
It is easy to say I would be rich if only my father had been rich but I do not think this is entirely true. You just have to see how many people win the lottery and a few short years later are back to nothing.
There are people who own some real estate properties and live off the rentals they collect and many others are jealous and think it is unfair but the truth is that managing rental properties is a full time job and that anyone who inherits a few rental properties and does not manage them correctly will soon be not the owner of a few rental properties.
On the other hand western European countries (generalizing much here) do have a serious problem with inequality getting worse. It is a complex problem and not solved by just saying "give them more".
The world is becoming more and more complex. A laborer with no training who could earn a living doing basic physical work, say, unloading lorries, today there is no place for such people because unloading lorries requires training, how to use a forklift, a license to use forklifts. a course and a license to handle foodstuffs with a forklift, etc.
Also we have become more complacent and less hard working. There has been a deep cultural change. From promises like "blood, tears, toil and sweat" we have gone to "Netflix, travel in Asia, Tik tok and Aliexpress". We are not the same culture any more.
If today someone ordered the light brigade to charge most would start asking questions, why? , are you sure? , Why not the heavy brigade? , Can't we wait until after breakfast? , OK then, you go ahead and I'll catch up later, etc.
As Mr Dylan said, the times, they have changed.
