It goes without saying that a parent will want the best education possible for their children. The only limit is what they can afford. It also comes down to a matter of trust. If I have the money will I send my kids to an established private school with a 100% pass rate (administered and adjudicated by international standards), or take a chance on a public school, where my school fees are  paid effectively to the government, and hope that my fees will lead to an upliftment of my chosen school? Ask the ministers where their children are being schooled. I'll bet it's not the nearest public school.
