If it's any comfort, every British person feels that Britain is going to hell in a handbasket, despite it being a very good place to live as a human being. All the French people I know feel the same about France, despite it also being a good place to live as a human being. All the Irish.. etc. Hell, Britain under Thatcher was, by accounts of nearly everyone I know who lived in that time, was appalling, but you still get people who wish for those 'good old days'.
The media and human mind portrays it all this way, that every 'Western' country in the world is somehow degrading and corrupting itself to the point of no return. And it's probably been the same since the dawn of time, once a country/culture has finished its ascendancy and reached a flat things seem to be getting worse, because things aren't getting better, just fluctuating slightly. Yes, China and India are experiencing a real boom currently, but it's the same boom we've experienced, in VERY simplistic terms they're 'catching up' to our levels of economic power per capita. And they too will reach a zenith, and worry that the country is beginning to fail.
My limited experience of life may be showing me up here, but I have a kind of confidence that the current problems in America, Britain, everywhere will be addressed when they reach the point that there is no avoiding them, or the circumstances change to permit a solution etc. New problems will spring up, the old problems will eventually re-occur, but nothing bar the fundamental problems of human nature seem to be permanent in society. And you've got to live with those.
OR Western civilisation is going to implode spectacularly a la the Western Roman Empire.
Go easy on me, I am young, this is mostly just to provoke alternate/more realistic viewpoints on such things to broaden my horizons.
