I saw this talk from Shlomo as well. Yes, it was interesting. He introduced a saving from people's raise, so that they wouldn't notice the difference. We have in a way done the same with our raising incomes, we have just never adjusted to spending it all and kept living the way we did when we had much less money.
It was the only saving-related talk I found on TED by searching. Thanks for your like with the other talks.
