Lol. I wondered why "Prager University" sounded so strange. Low and behold, this "University" is actually a youtube channel run by a conservative talk radio show host.
Regardless, the basic info here is correct, but they gloss over the part that is actually important. Obviously you want to increase growth and cut spending. Every government would like to do that. That is easier said than done though.
Reducing government spending has a direct negative effect on the economy, and visa versa. Finding the right balance is what politicians have been fighting over since the dawn of time.
