It's a tough question, because my income is down at least 30%, so plainly we are used to having more.
On the other hand, we certainly "get by" and then some. We've given up some things - we used to have a vacation home and used to go out to eat once a week, we gave up HBO and Cinemax, but the vacation place was too far to drive now, and we don't miss eating out and hardly ever watched these things anyway.
We have a nice place to live, clothing, food and high speed Internet :-)
So we don't "need" that missing money. We are happy. I can't help thinking about people who have lost their jobs or their homes or both. We have given up really nothing by comparison, so I just cannot complain.
