Quick question, kids switching to private from public that don't play sports do they repeat a grade, especially on the parent dollar? Very doubtful!
Rich kids repeat on their parents' dime all the time for behavioral and/or academic purposes. There are tons of spoiled brats who play no sports and spend extra years in school as parents find ways to boost GPAs and SAT scores so their lazy overprivileged offspring can slack off in an ivy league school. Yes, I know lots of lax kids named Blaine, Bradford, Thatcher and Brooks also fit the bill, but there are many more pothead holdbacks that don't play lax (just look and sound like they do).
