Yes, the Economist has an article on this relativity every two years or so :-)
There are two reasons for why people invariably choose 2>
- people are competitive and want to feel superior to others (or at least above average)
- the price of everything adjusts to median income, so if you live in a $60K state/country with a $75K income, everything is more affordable for you.
Depends. Can I opt for the $100k income and then move to the $60k neighborhood?
I highly dispute this. Take it as a completely different world view but I think if people were given a choice:
1 >a nominal income of $100k for you and a nominal income of $200k for all your neighbours
2 >a nominal income of $75k for you and a nominal income of $60k for all your neighbours
A lot of people would opt for choice 2. I myself am not sure whether I'd go for 1 or 2.
