The debt crisis
Political polarization, especially in the us.
Which prevents the first from being dealt with.
The flight from science and logic to soundbites and dogma.
The loss of manufacturing capacity in the ,,west,,
Enviromental collapse. Global warming.
Im not saying these are indicators of a collapse of the west, but if it does collapse, they will be pointed to as such.
Otoh, people having been pointing fingers and predicting collapses for half a century now and weve managed to stumble through all the crises more or less successfully, so far.
