At one point in the Planet Money interview, I believe Wolfers did say that when it comes to happiness, someone (Kahneman, I think) had estimated that there is a satiation point at around $75,000 per year.
Is that enough $$$ for you???
As a single person, living where I live, if I just bring home $40,000 a year.....that would be more than enough for me to live a very satisfying life when it comes to my basic needs and more than enough leftover for me to entertain myself in a entertaining way.
On the other hand, if I were to live according to my most carnal and greedy desire, I estimated that I would have to take home at least $10,000,000 a year to have enough to live the way I wanted to live.
Keep in mind that even if I bring home $10,000,000 a year, I'd still have to rent or buy a used private jet. The one I wanted to buy is just not within my measley $10 million budget.

$10,000,000 dollars is just not a lot of money these days.
