The problem is that it can not be because of money, the major central banks are priting money in a non-stop basis, this is making them everytime more richer.
They do not care about the inflation, they do not care about nothing, because we all know that the united states can not stop printing bills, and that is why their debt is so huge.
But it wont collapse, they are the major potency, and it wont change.
The forth revolution will not be caused by money, it would be caused only if banks decide to start a new revolution, not about bitcoins.
