Again if you aren't sure if you are rich, you probably are..

Edit

There is a far bigger range of people who are all wealthy compared to 90% of the population. They just don't feel wealthy compared to each other.

For the purposes of the discussion let's say poor is anyone who can't afford basic nutrition, housing, thermal protection, and transportation.

Obviously these things depend on market and realistically include other costs like healthcare, childcare, etc. Point here is there are levels of poverty, but generally people who can afford all of these things and can build a safety net are not "poor".
