You really think that? There are a lot of families that got rich in the early 20th in the US who are still controlling huge stakes in production of the country. After a 100 years I'd start calling those dynasties.

Countries you cited have had the bad luck of having much of their means of production wiped out through war/political turmoil. But the places that haven't blown up... well the wealth doesn't seem to be moving as fast as you seem to imply .
