Maslow's hierarchy my friend.

At the fundamental level, when you dont have the basics, money certainly buys less sadness. However, as you work up the chain (and income scale) money loses it ability to impact in that way. I believe a study was done that it was $70K in the US. Up to that point, money created more happiness but after one passed $70K, the impact was negated. Someone making $300K wasnt happier than the one making $75K, at least because of the money.

Great post. Followed you.
