The march of science and technology does not imply growing intellectual complexity in the lives of most people. It often means the opposite.
Most people who offer their help do it to make themselves feel better, not us. To be honest, I don't blame them. It's superstition: If you give assistance to the family in need... if you throw salt over your shoulder... if you don't step on the cracks, then maybe you'll be immune. Maybe you'll be able to convince yourself that this could never happen to you.
