History tends to support your conclusion, but most of the time high concentration of wealth leads to social instability and then (bloody) revolt, overthrow of whichever 1% runs the show at the time. Then the (+/- 70-100 year) cycle starts again. It seems it's best to be born about 10-20 years after each of these crises (see Baby Boomers). It's worst to be born just before / during such societal quakes and unfortunately, we seem to be on the cusp of a new one now. I would add that that before the change occurs, there is inevitably a long period of oppression first as the privileged try to defend their positions, with increasing amounts of suppressive behaviour. We see that already with the surveillance society in which anybody who might challenge the current powers will be branded a terrorist, and even in the economic policy of QE which has the main effect of supporting the financial interests of the wealthy incumbents.
