Interesting discussion.
I've thought for many years that the upward spiral of the standard of living would have to come to an end or at least slow down. Neither of those possibilities bothers me too much. I can adjust to a gradual shift. What is frightening is the "collapse" of our standard of living which may be in the works. When the net lenders decide to stop lending, the party will truly be over. Then, we might find ourselves back in "the good old days". Except they weren't all that good - and it will be difficult to adjust.
Since the majority of posters so far seem to believe we are at the end of an era (post WWII boom or bubble) do we have strategies to deal with this scenario? I have built considerable slack into my FIRE plan, but if the whole game has changed, I'm not sure there are any obvious moves. We don't even know if we're headed for deflation or inflation in the future. Makes planning problematic, especially for those of us who've already committed to retirement.
I'm pessimistic by nature, but it sounds like I'm not the only one at this point.
