I think I'm actually quite a materialistic person, I value what it takes to make a car or build a nice house. Money does change things, but how it changes people depends on how they react to it.
The first duty of a human being is to assume the right functional relationship to society - more briefly, to find your real job, and do it.
I have the responsibility of over four million people, and I am in a position to do good, to be able to bring about a new life for my people, and I will continue to move in that direction. It's a burden, but it needs to be done, and you have to have the courage and wisdom to see it through.
