In my friend group, our incomes vary by about a factor of 5. We all spend about the same, though. Which means those that are making more are much more comfortable, putting money away for a rainy day.
In contrast, a college friend that keeps in touch makes more than any of us, but she likes to lease new cars every three years, and she must spend money on the poshest pre-school in the area, and she is shocked to hear about people saving $2/3/5k a month. That's money that could be spent!
I don't think I have a point here. I just can't wrap my mind around people making $150k and not being able to "raise $2000" in a month's time.
