Re: Greece! I do agree with you that we go through cycles and aren't facing a doomsday. (It could happen but would take some truly horrible decisions to be made that just aren't likely to happen.) It's also true that more people tend to become wealthy over time. The bad thing is the division between the wealthy and the poor is becoming much greater over time.
Consider the classic example of the difference between an entry level employee in a company (say a secretary) and the people at the top (say a CEO.) In the 60s the difference would have been on the order of 10x. Now the difference may be 40-50x. That shows that while there may be more rich people it does seem that the money tends to move towards the high end.
