The liars, the manipulators of this world hold the reigns- precisely because of those traits (the 3 or 4% of the population of psychopaths and sociopaths).

It has always been so. But historically, smaller social groups, through ostracism, maintained a (relatively) control on society.
The rise of these 4%, and their power, because of larger social groups, has been to the massive detriment of us all.

So hidden technologies, Ufo's, and the hidden knowledge that goes with it, is just seen as a tool of control (by the 4%).

Their concept of 'greater good', or 'doing the right thing', is not even a concept to these people.
It's not even present in their universe.

Until this problem is addressed, and remedied, everyone can kiss any progress for all, goodbye.
