What would happen if EVERYONE taps into their subconcious?

Imagine if everyone in the world was capable of using 90% of their subconscious.. Wouldn't that be amazing? Yeah, not really.
If everyone in the world was capable of telepathy, telekinesis, mind reading, and all those other mind powers that i cant think of right now, we would be thrown into a millennium of pure chaos. How you ask? Most people will begin to think that they're more superior then other people, and with thoughts like that, that would lead to some chaos.

But imagine if we had someone like Hitler, or Musolini, in our time and era? If they were able to use the 90% of the subconcious, could you imagine what would happen? If they caused such destruction in the 1940s with the little amount of technology available compared to nowdays, now multiply that by about a million and 5. That would be only alittle bit of the destruction they'd be capable of if they were able to use their subconcious.

It would be end the of mankind, if we're still alive after the world gets nuked during World War 3. Okay, not entirely accurate, but it's possible that we'll have a third world war.

It seems like a good thing that we can't use all of our mind power. And it probably is.
