Upward mobility in US means you have 1. no arrest records, 2. perfect credit., . Else you fucked in US for life, forget about career at US Corp., want to start business with that record, forget about loans. Most African Amer. would find themselves in that category, and NO they are not more criminal , it is idiotic US justice system that thinks smoking joint is arrestable offense.
Regarding posting charts:
The fact that wages have been stagnant for over 10 years and then the fact that comparing generations of fathers and children is laughably retarded without adjusting for inflation , consumer basket purchasing power and the fact that previous generations of mothers in US stayed at home, yea genius = one-income family vs two. They averaging to family of 3 where two people work vs. family of 3 where only husband worked = that methodology is for idiots.
