Editor’s note: Donald Trump regularly incites political violence and is a serial liar, rampant xenophobe, racist, misogynist and birther who has repeatedly pledged to ban all Muslims — 1.6 billion members of an entire religion — from entering the U.S. [spoiler]Not at all a bias article- not something you really want when you're trying to disprove an economic theory[/spoiler] The funny thing about academics especially economists is that they pretend like they have discovered the answer to these questions such as what exactly is the government spending multiplier, how much do people rely on the 'animal spirits' to spur investment, the liquidity trap, etc. but the reality is no one knows the answer because if they did, well the field would cease to exist. The two foundations for economic thought have essentially been thrown away- classical failed with the long recovery of the Great Depression and Keynes failed with stagflation. There are pros and cons to leaning one side or the other and it's best to weigh those pros and cons rather than pretend like there is a right answer.
