We can skip past the question of whether money changes people or not. People change with their circumstances because we are products of our environment. My curiosity is whether you believe that should be the case. Is it within our capabilities to retain our moral principles, manners, and respect with the development of good economic standing.
Like most things, I believe it as possible as you will it be. Mind over matter. To me, it all depends how driven someone is to remain true to themselves. What do you think?
