Was it actually better during the "good old days" or does living in the "information age" make us all just that much more aware of the apparent "deficiencies" in American democracy - people aren't lined up at the borders requesting US citizenship because they view this nation as a failed "experiment!"
I contend that the more "deficiencies" that are brought to the public's attention, the more critical we become - with the many positives that we take for granted being pushed aside!
There is that. I think the decay we see in political discourse has a lot to do with the fact that some groups are now doing much better in terms of rights and income than they did 50 years ago, and some other groups are doing somewhat worse. It's natural to blame those people and seek a solution that can restore the way it was.
