I would like to know why Carnegie said " Give this gentleman 16 cents"
On the Lighter Side
A socialist once came to see Andrew Carnegie and soon was railing against the injustice of Carnegie having so much money. In his view, wealth was meant to be divided equally. Carnegie asked his secretary for an assessment of everything he owned and at the same time looked up the figures on world population. He did a little arithmetic on a pad and then said to his secretary, "Give this gentleman 16 cents. That's his share of my wealth."
The joke is that the socialist argued that Carnegie's wealth should be shared equally by everyone. Carnegie asked his secretary to divide the amount that Carnegie was worth by the number of people in the world at that time. The result of the calculation was that each person would get 16 cents - so that is what Carnegie tells the secretary to give to the man.
"On the lighter side" is a standard phrase to indicate that there is a joke following. It means that whatever follows is not very serious.
