Its very strange to listen to this kind of certain, idealistic tone when relating to things that we just don't have certain knowledge about. In macroeconomics, the relationship between fiscal spending and unemployment/economic output is unknown. We've been arguing about it for about a hundred years and we are not really any closer and answer. It may be that an economy is too complex to explain the way we've been trying. It would be like trying to predict the effect of releasing magpies on the squirrel population of a forrest. A weirder example is nutrition, diets. We have different schools: evolutionists / paleo, low fat, atkins/low carb, weight watchers, all about - calories, all about growth hormones... They all have mountains of anecdote and a powerful conviction that they are right and everyone else is a blind, stubborn idiot. These Atkins idiots don't believe in thermodynamics. Calorie counters think we have furnaces for stomaches. Neither believe in evolution. So.. obviously we don't really know why this generation got so fat or what individuals should be doing to reverse it. Naturally that doesn't stop people from being incredibly confident that their theory is undeniably true. Tellingly, they are mostly associated with charismatic motivators more than scientists or experiments. This thread is back to back proof-by-contrived-metaphor.
