Couple of things (and I am being serious for a change)
1) Those that enslave us need us to keep on working. Currencies may come and go, but the financial system will never truly melt down, just possibly be replaced. Global currency being the next step (around 8-10 years is my prediction.
2) Unless you are working for Wall St or Goldmans you cannot know what is going to happen. The markets are all manipulated.
So in short, stop worrying, start living, make the best of what you have and think yourself lucky for what you have. Those that enslave us know that by keeping things cushy we will not make too much of a fuss. In fact this is born out by the fact that we are more prepared to winge about someone getting unfairly getting kicked off the X factor than lobby parliament by the tens of thousands about "unfair" changes in child benefit, for example.
Prolly get flamed for posting this, but if you think about it, we've never had it so good.
