The nouveau riche are like the rays of the sun, they have no progeny or no real connection to progeny so they disappear, sheeted off as radiation and are replaced by the hard working molecules from the inner core, like an economy pushes nouveau riche to extinction replaced by hard working immigrants….if they stop immigration, we have the same effect as an imploding sun, the sun runs out of hydrogen, the economy at core supergravitates that it is taking the slack for the workless radiant layer without relief by new immigration taking up the hard working slack and the radiant layer collapses into inner core and an economy implodes then disintegrates, is what happened to super wealthy Mughal India and is now in play in USA, working class denied the easy economic growth of hard working immigration.
