i don't think i did. however, the motivations for most people to live where they live contain the word "I" in them. but i don't believe that is totally evil or wrong either. we got to live for ourselves to some degree.
i moved here becuase i like it. i like to climb. i make money that i spend on myself. all my choice. the reason i don't give more to charity is because i do all that for myself. i take that responsibility and whatever judgement that goes along with it. i can't say i wish i did more. once i do that then i play the victim. if i truly wanted to do more i'd not spend so much on myself, my condo, my car etc.
those that chose to live in the midwest do so for probably a lot of the same reasons (minus the mountains)(but they have their own hobbies) their excuse for not being more charitible might be different than those that use the mortage excuse.
either way it all comes down to priorities.
