Research suggests that children who attend pre-k fare better later school and in their careers. By making early childhood education contingent on a parents’ wealth, we’re giving rich kids a big leg up. But we’re also making it more difficult for low-income parents to work. If a child isn’t in school, someone has to take care of them. Sometimes that’s a daycare program. But for families without access, it probably means a mother has to stay home, taking time off from the workforce, and setting back her future career. So in short, this is all just a reminder; For those interested in fixing inequality, whether it’s gender or class, making nursery school more available to all wouldn’t be a bad place to start.
