These are nothing but assertions of fact which are really unsubstantiated opinions. It is striking to watch people engage in this level of intellectual onanism.

I dont mind people making arguments that are reasoned and carefully successively built. But to just start with one opinion, pretend it is a fact, and then build another assertion on top of that is a bit much. I do not believe that you have to have a degree in economics to opine about economics, but whatever your arguments are, at least make them as arguments as opposed to "I am smart so everything I say must be true" style pronouncements.
