So to answer the question, 47% of people nationwide cannot come up with $400 without borrowing or putting it on a credit card.
NC has a predominance, 90 out of 100 counties, whose average income falls below the state average, many with average incomes 25% below state average, which would raise the 47% number considerably. 20% (2MM)of the population of NC receives Medicaid/CHIP and families of three making $40K are eligible for SNAP.
Since schools are paid from property taxes, it is obvious these poorer counties cannot compete with the wealthy counties in the quality of education (Wake and Durham supplement teacher's salaries by ~$7K a year) and it shows if you research US News top US/NC high schools. The best schools are in the few wealthy counties.(5 counties account for appx 50% of the state population)
Although North Carolina teachers received the largest average pay increase in the country, NC [Average] Teacher Pay Was Ranked 41st for the 2014-2015 school year placing NC below SC, TN, VA and the national average. Over all NC was ranked 34th -

So outside a few counties in NC, the state is rural, mostly poor, has substandard teacher salaries and schools perform 34th out of 50 states.
