Read the micro 101 and macro 101 textbooks used by good universities. Principles of Economics by Taylor is one of the common textbooks. Macroeconomics by Mankiw is another one. Intro courses on any subject tend to be very accessible to laypeople. Sowell is unserious because he misrepresents the other side. He basically argues that when you leave everything for the market to figure out it will automatically turn out alright, and if it doesn’t then clearly it means you need to deregulate more. You can look up what the arguments against complete free market solutions in healthcare, housing, education, and manufacturing are and you’ll see that the “obvious common sense market based” solutions don’t produce good outcomes for society.
