Adam Smith was right when he said in his book “The Wealth of Nations” that it is demonstrably true that the social good is best served by pursuing private interests. People act in their own economic self-interest by working to produce goods and services that others will want to buy and use. It just so happens that by doing that work, many other people receive benefits as well.
Besides, don’t fool yourself, people in government act in their own political self-interest, because that will allow them to obtain and stay in office.
So, as Milton Friedman asked, how can you believe that one person’s political self-interest will somehow be more noble than another person’s economic self-interest?
