modern america's education pipeline is seriously corrupted and was corrupted on purpose to prevent social classes (ie, ghettos) from excelling. Most of this stems from the 60's desegregation and what should be called the "cement pool" affect, where white people, rather than allow desegregating public pools, filled these pools with cement, ruining the public asset for fear of intermingling.

Instead of allowing races and women into the public benefits sphere, they slowly dismantled the social safetynet.

In the specific instance for education, pushing state funding onto the city property taxes and school districts ensured impoverished areas would continue to fund impoverished schools and as the decades wore on, this tightening of budgets bled into it's surroundings and then the dismantling of funds as per-head attendence started via magnet, charter schools and now school voucher programs for private schools and the rest.

This is a pipeline designed to punish society for integration. this is "critical race theory" in the next 5 decades.

You can blame it on techno culture, but that's just the indirect cause of fundamentally desociallizing/devaluing public assets. You can make a direct association, also, with the rise of the business class as another attack on normalzing this type of segregation without laws.
