Besides money buying materials, why do people think so much of it?

Because the love of money is the root to all evil you can’t serve two masters because you will love the one and hate the other. Money is not the issue it’s the love for it that hurts. The Bible and God didn’t say we couldn’t have it God just said put your trust in Him and He will supply you with all you need.

People like power and to impress others. They don’t seem to care that this is a sin. They only care about what they can acquire today.
