Strange that the Koch brother mole, of all people, does not not understand supply-side economics. Also strange that they are seemingly in favour of kommunalkas.
I don't think it's a misunderstanding of supply and demand. There can be an explanation on both sides of the equation. Increasing supply is a solution to increased demand, but it's worth sharing that demand itself has increased and why it's increased.
Take a look at chip shortage a few years ago. Demand went to about 5x normal demand in the space of a year. The solution was to increase supply but it's not a misunderstanding of supply and demand if you told me that demand increased for xyz reason.
That's the thing about propaganda, er, libertarian economics. You have to promote whatever the spin is today, even if it contradicts what you said yesterday. Their followers have etch-a-sketches for brains. Shake them upside down and they are blank again.
edit: I guess I called that guy wrong. Anyhoo, everybody who has read The Road from Mont Pelerin all the way through raise their hands. Only me? The prosecution rests.
