you’re measuring the wrong thing. Spending more on education if a child’s home life is garbage is a waste of time. That’s controversial because it doesn’t sound nice, but it’s a fact. The real problem is not at school and school can only help so much.

At a broad policy level, government should focus its effort in other areas of basic NEEDS first. Stable jobs for parents, housing and food needs met, etc. Being a successful student when your families basic needs are not met is an uphill battle.
