Most of those people are actual viruses. Just like agent smith said in the Matrix. They gather exorbitant amount of money and what do they do with it? Muddy the waters, making sure noone comes close to them, feed absolute hogwash to the masses, even write books about it (This is the secret how you will succeed as an entrepreneur etc etc.). And more and more and more people fell for it. And they spend more and more time trying to untangle the bullshit. And that takes time and then they gave up. Viruses, nothing more, nothing less. There are exceptions, but very very few.
