What is wealth?
The landowners were rich. The land was real wealth. Also, wealth is slaves. Slaves cultivate the land, and landowners get rich.
Then loan capital appeared. Gold has become valuable. Derivatives for gold, such as promissory notes, emerged. The bill is very handy if you are traveling.
You made great points! I tend to agree to the most part, however, I believe with the emergence of financial elite, the history might not have been exactly as you described. Even the largest industrialists were financed by banks and investors (i.e. financial elite). Even during the WWII war, Hitler was financed by elites. With tech millionaires, same - they obtain capital from VCs who in turn have LPs in the form of banks, insurance companies, large funds, etc. - thus also, either directly or indirectly financed by elites. You cut their cheap capital flow and they all will die together with their "unicorns". And that's just the surface fin elites, and we didn't even discuss the Fed, BIS, IMF, WB, SWIFT, and those supranational ones who exist above and beyond the state's reach.
Yes, everything I've written is a simplified version of what's really going on.
For example, most modern landowners in Great Britain are families with lineages dating back to the time of William the Conqueror. This is a testament to how slowly the change of elites in the world is.
Landowners, financiers and industrialists rule the world at the same time. They interact very closely with each other.
Nevertheless, each stage of technological development gives new people a chance to become members of the global elite.
Early Bitcoin holders also have this chance.
