Increasing teacher pay for one would help close that gap.
Across this country, teachers have been on strike because they are badly underpaid. They lack basic supplies, work in rundown classrooms, and their professional expertise is undermined by excessive standardized testing that takes the joy out of learning. Far too many are leaving the profession entirely.

This year, the situation has become an emergency. The start of school saw a 16 percent increase in unfilled teacher vacancies, and teacher pay was well below the national average. Adding insult to injury, under President Trumps new budget, South Carolina would lose $28 million of grants to help high-poverty schools boost teacher salaries. Overall, South Carolinas public education system would lose roughly $246 million under the Trump budget, denying 14,000 students access to after-school programs.
This endemic lack of investment in teachers, public schools, and educational opportunity is particularly acute in rural communities. Kids are starting kindergarten without basic skills: Some do not know how to recite the alphabet or spell their own names.

Having said that the average is not so important as the humanitarian shift in policies in total dollars spent.
We can either keep funneling our tax dollar monies to a 21st century form of slavery which in turn has a dampening effect on wages of free Americans or help our fellow Americans rise while making our nation stronger as whole.
