I’d guess almost everyone here is in that red section (or the dark blue above it).
So, it that trend healthy for a country? Any country? Can a country withstand just a few people controlling more and more and more wealth (the trend is exactly what many of us predicted decades ago).
I’d say it’s getting more unhealthy and wouldn’t be as bad as it is now if richer people couldn’t pick up the phone and call politicians and get tax cuts, legislation in their favor, regulations voided, preferential treatment, etc). If the playing field was level (so, say, republican posters here had as much clout as any other americans) the wealth of the country wouldn’t be sucked upward to a small number of Americans (while the rest live paycheck to paycheck or can’t pay their bills).
I think the people in the red and dark blue are suckers.
