First off, mainstream = corporate, so Money and Time? Not hotbeds of social justice.
Well, let’s not assume that a 100% social justice economic platform is workable. Lots of ideas sound good on paper.
Second, all those articles are about nouveau riche, not the dynasties.
Part of the point there is that on a % of economy basis, we have fewer dynasties than other nations do, particularly in Europe.
Oh, and yeah, you’re selling trickle down, you just don’t like to call it that.
There’s no such thing. But, believe whatever mythology you like.
