@hawkeye10,
You're entitled to your opinion. Certainly Europe (and just about every country or assemblage of them) faces a number of sometines unsolvable-looking contradictions. However time and life roll on.
The immigration Europe is seeing right now has been going on (albeit at a lower level) for some time. If they are able to work out the attendant social strains, this could be a solution for their demographic problem and the economic issues attendant to it. Certainly immigration has been the fuel for our own economic growth.
For all the criticism and second guessing they'ver been taking, the German government does indeed appear to be working hard to restore some badly needed economic discipline on the union. At what point does "stripping the dignity of the hapless Greeks" become "preserving the economic and monetary health of the Union" ?
Europe is a dense concentration of different languages, cultures and history. For all its visible defects the EU has done a pretty good job maintaining peace, stability and rconomic growth. If you doubt that, just consider the two previous 50 year periods.
You and I apparently generally agree on the extent and nature of the challenges facing the EU. You appear to see them as fatal. I accept them as serious issues, involving some risk, that must eventually be dealt with. At the same time I note that the evolving union has already successfully dealt with (or skirted) many other like issues, and hope for its continued success, recognizing that the alternatives to it are surely worse.
