The end of western democracies ?

So as the US stock market starts to weaken, is this the end for the strong dollar ?
With the end of free trade world wide is that the end of world economic growth ?
With the end of strategic alliance across the Atlantic is that the end of world peace ?
With the birth of a new great depression is that the start of runaway global warming ?

These things are structural changes in the world order that will haunt us forever unless soultions can be found and I see nothing in the current situaiton to give us hope of a brighter future - the attitude of the world has to change before thing can get better. The attitude of the world is not changing, positions are just becoming more entrenched and hostility is rising. How can we the people stop this ?

In a world dominated by democracies - how are we letting dicatatorship rise and triumph again ?
In a world of shrinking resource and overcrowding of habitable lands, how can democracies based upon continued economic and personnal wealth growth even survive ?
This looks like its very much the end - sad to say - and we let it happen on our watch.

Sorry to sound pessimistic but "united we stand, divided we fall."
