I am a public school graduate and I am a CPA. My kids go to public school and are very intelligent. Sorry we don’t have a $1,000 a month to put them in private school DipSh*t.
Anyway, I'm a public school graduate and make twice that much so I could easily have sent my kids to private school. But I chose not to because I wanted to use my money for something else - like vacations and retirement.
With good reinforcement at home, there's nothing embarrassing about choosing to send your kids to a public school. The parents have more to do with educating their children than any school - public or private.
