That isn't deceptive.
That's just an average same as all the other countries.
And it's a low average for a 'developed' country.
Just like their teachers' wages.
Pay better salaries, attract better people.
It's only the country's future at stake.
Except that the average is very misleading, since U.S. education is very decentralized in some respects. Even within a state, there are degrees of better/worse school districts.
