What's the connection of economy to school?

I saw my boss laminating some "dallant" (points that children collect and use as their money during the dallant day that is usually done during Children's Day and Christmas) when he said that Korea is now facing difficulties on its economy. It's true because the former rate of $1 was less than 1,000 won and now it's 1,328 won. Because i'm not aware of the economic growth and I don't care anything about the government and economy, I suddenly asked him what's the connection of the economy to his school business. He said some parents will not send their children to private institute if the economy is very low. Oh yeah, that makes sense. He has the right to be worried! hehehe...
