Everyone wants to be smarter, or if it is too much to ask: wants to look smart.
But why? Because of what? To what end? What would smart get you?
For some people it would help them produce results in whatever they are doing... For others it would get the promise, the mirage of being able to produce results... and they hope that they won't need to actually produce anything.
Because you only get your rewards, with actual results. In a normal world, in a world where people act rationally. Obviously we don't quite live in a normal world...
Very few people do what it takes to become someone who can produce.
