>If the economy falls behind then quality of life will follow at some point.
If only Europeans would accept this truth and wake up that something has to change yesterday.
What's happening to Greece is just the mining canary for what's gonna happen in much of the rest of EU later, if there's no preventive change of course.
Only partially true though. A rising tide can lift all ships. The EU can benefit from advancements in the US invests in because of our wealth. This goes the other way as well, even thought he EU isn't putting out as much, they are putting out something and that benefits the US. So long as they don't fall so far behind that it isn't worth trying to bring them up - but this is unlikely, I'm not even sure how this could happen.
Noone claims that people in the third world enjoy great quality of life, for instance. You can't benefit from the advancements of others if you cannot afford them...
> I'm not even sure how this could happen.
It can always happen but it is gradual and takes time. Places like India or China were once the richest areas of the world, only to fall behind and become among the poorest later on because they stagnated while others progressed.
That is why it is partially true. There are many other factors as to great quality of life. If you have all those other factors as well then a rising tide can life your boat too. Some third world countries have seen this over the years, and others are seeing it now. Some have seen it and then something (often a coup) reverted them to bad quality of life.
If the economy falls behind then quality of life will follow at some point. In fact quality of life is already not so great and decreasing.
