That's very kind of you that you'd want to help out the less fortunate if you had more than enough money.
About the quote though, I do agree that chasing money is unhealthy, but it's also true that a certain amount is necessary to stay happy.
You can't expect a poor person to be completely happy with their lives if they can't even afford food or medicine or a roof over their heads.
If you're not healthy, no matter how much you try, you can't be truly happy. At least that's what I believe.
