I agree. I guess buying power in general is a better way to judge. How about the ability to take a family of four to Disney World on vacation? IMO, if you can take a family vacation with less stress than four years, that is an accomplishment and you are better off
I'm not sure. I think that single measurements like this will always be a pretty inaccurate way of knowing how strong the economy is. I honestly don't know what the best way to measure the economy as a whole is. Probably some combination of CPI, unemployment, wage growth, housing prices/construction, and GDP. And even that is a macro way to look at things. The economy of one city to another is going to vary to some degree.
Sometimes I think people look at the economy as sort of "vibes based", and depending on the political climate they are biased to think things are going better or worse than they actually are. I prefer hard data, as always... but what exactly the criteria to measure is certainly up for debate.
