What main point about wealth and responsibility does Carnegie make in this passage?
Nature's laws have caused society's most fit
members to build great wealth.
O Wealthy people should live modestly and
purchase only what they need.
Rich people should use their wealth to benefit
society.
DONE

In my opinion, mind you this isn’t a question where only one answer is correct.

He’s saying that due to survival of the fittest, nature’s laws, have created the fittest people to be the wealthiest, and those that aren’t wealthy aren’t the fittest. Saying that the rich should live just as modestly as everyone else and use the rest to bring up those in society to the wealthy level. Giving back to society is the only way to create more of nature’s fittest creatures.
