I have not noticed a general decline in Humanity as Ziirp mentioned, though I half agree. What I have observed since at least about the year 2000 is an increased polarity between, well...lots of things. Equality, especially financially is a big one, and with increasing polarity of ideologies, whether politically, socially, religiously, and many other examples. We witness this everywhere. Even the two 'primary' Political parties have been split in half this election cycle, when Bernie was pushed out of the race seemingly through corruption, and half (I hope if not more) of Republicans can't support Trump for one of a million reasons.
Technology 'promises' to bridge some of that polar rift as we continue to get third world countries universal Internet access. I think when the people realize the true power and potential of this technology, things are going to change, people are going to organize and govern themselves increasingly, regardless of how hard Corporate and Political Establishmens fight back. The good thing is that this 'third world war' will hopefully be fought not with bombs but with information and human connectivity.
Just my perspective.
