One thing I will say is that there is no said definition of "rich." I have to remind myself of that, that the term's definition changes for everyone. I personally dislike the term.
I live in a comfortable place, I never have to worry about getting enough to eat, have plenty of clean drinking water, have access to good friends. I make a living, and have savings should I need to draw upon them, I'm not overly worried about getting mugged on my way to work. If I ever want to cook, I have plenty of access to groceries, and should I ever decide to splurge I have hundreds of restaurants I can go to, where a staff will be geared towards serving me. In short, I have a better standard of living than over 70% of the current populace of the world (might be exaggerating the number), and probably live better than the richest person living in 1818.
