True, but if you never read nor marxist nor Sowel like basic literature, than how would you know that you are aware of the basic economics in the first place?

True, but if you never read nor marxist nor Sowel like basic literature, than how would you know that you are aware of the basic economics in the first place? and if the only literature on that topic you've read is a special kind(only marxist for example) than it's likely that no matter how intelligent you are, but your way of thought has been overly influenced by one school of thought. My general position on political topics like this, is to start with reading literature that is somewhat widely adopted but foreign to your own views, like if you are libertarian leaning to force yourself to read leftist philosophers and theorists. This guy is basically opposed to libertarian philosophy, so using the term basic economics and not reading a book with the same name, from one of the most well known academics with libertarian views(or showing understanding of it's contents) is at least weird.
