Perhaps the Democrats and Republicans calling the shots aren’t up to the task.Again, if democrats would do their jobs and fix their schools, there wouldn't be an educational gap.
You know some places that went from pretty low educational standards to much higher ones?
The USSR (under Lenin/Stalin)
China (under Mao)
N. Korea (under Kim Il-Sung)
Cuba (under Fidel Castro)
Grenada (under Bishop)
Nicaragua (under the first government of Daniel Ortega)
