lots of good points here!
Rich is relative too. What would salary would make you rich in one town or stater, wouldn't in another. If you live in a town that the average house $150,000. $60,000 a year goes far. If you live in a place that the average house is now $500,000, the same $60,000 doesn't go far.
Also it is what others have pointed out What you think is rich. For some having a decent house, car, food on table, vacation once a year is rich enough. Others feel if they don't have designer clothes, luxury cars, mansions then they are not rich.
I think it comes down to if you are not happy with yourself inside, it doesn't matter how much money you have because money fix everything. Buys lots of good things but not everything.
