As you can see in the WaPo article I linked, Pennsylvania is a huge outlier. Nationwide, including state and federal funding, poor districts get only 1.7% less than rich districts. In many states, like Maryland where I live, poor districts receive slightly more funding.
On average in USA poor inner city school receive 15% less. That's the actual numbers. Some states have a more fair funding system and than there is PA. BUT if you look at the bottom states in Education, Miss, WV, and VA they allocate less money to education. In PA a teacher makes about $42,000 first year and in WV you get $28,500.
> When federal dollars are included, just five states are spending less in their poorest districts than in their wealthiest. Nationwide, the average disparity drops from 15 percent to less than 2 percent
