All good points, but my delusions rely on one piece of magic: determined people from disadvantaged backgrounds can become successful anyway. This won't all be fixed in 15 years, but it will start to be fixed just by numbers. Yes, the current numbers are awful, but they must get better in the future. If they don't get better, the US will end up as 90% poor and 10% CEOs. Many racial-cultural ghettos throughout the country do exist and drive down the future potential of millions of children, but everybody won't stay there forever. Maybe it only takes a few breakthrough tech successes to set the stage—people to look up to, not "smart is bad" culture. (Also, with current numbers, there are isolated pockets. Sure baltimore is 65% black, but that doesn't put pressure on employee availability (employers can relocate people from elsewhere). But when the entire country is 80% mixed hispanic-white-black-chinese in 100 years, employees must come from society as a whole somewhere.) It is a generational problem and it will take another one to three generations to fully be considered a non-issue anymore. (Assuming, at some point, the US decides to invest in education and children and growth again instead of choking off all avenues of social mobility as have been routine for the past dozen years.)
