True indeed, the problem is that at every time in human history the system and those in charge would benefit if those under them wouldn't have all the information because if they do they it would be much harder to manipulate them. Today we have can find almost every information on internet but the system doesn't give us enough time and space to do that, also unfortunately it is in our nature we don't want to think about all the info and if it is true or not because how would it benefit us in the system that doesn't want us to do it.
