You can be taken seriously after you actually complete a university-level course in macroeconomics and microeconomics. I am beginning to suspect you are not even old enough to have completed your high school education yet.
Um, dude, I teach economics at a university.
Yeah, and I won both a Gold Medal in the Olympics and the Nobel Prize in Economics.
As the story goes it is supposedly some Thai university which doesn't know what it's doing. So it doesn't say anything about his ability, of course.
As Opebo has admitted to in the past, he doesn't actually know anything about economics. It's sometimes amusing to read his attempts in the field but it often becomes painfully pathetic.
