Why shouldn't a student go to private school?

In private schools, there is better education since, it isn't government owned so, some of the subjects may be picked from the school board. That's why there is mostly religious private schools. As well, there is a lesser percentage of bullying, and fighting, because most private schools are close knit/family-ish since, there usually isn't alot of students. So, basically everyone knows everyone and gossip/rumors get around fast. Also, there is more one-on-one education/teaching since, there usually isn't alot kids in one class--unlike public school which has like 24+ kids in one class.
