Greece’s European partners demand changes that the average Greek doesn’t want to make. Greek politicians so far have tried to square the circle by making loud declarations about how determined they are — while making some changes but putting off the most painful ones. That strategy is now running out of time; to keep the bailout funds coming in, the government will have to fire tens of thousands of government workers in the next few weeks and otherwise behave in a deeply unGreek fashion.Meanwhile 9 out of 10 voters disapprove of the government’s economic policies, and the economy continues to shrink.The Biblical story of the Tower of Babel is looking more and more apropos these days. That story recounts how God divided what were then the unified people of earth into different nations by ‘confusing their tongues’ — by giving every people its own language. Those peoples would go on to develop separate cultures and cooperation between peoples would always be a chancy and difficult thing.Different countries have different political and economic cultures; not everybody is willing or able to play by German rules, even when they know that playing by those rules will pay off in the end. Governments must make policy for the people they have; there is no point in trying to turn Greeks into Prussians.The idea that Greece will ultimately have to leave the euro zone is being discussed at higher and higher levels around the world. The time has come for the Greeks to put contingency plans together, and for the other euro countries to take steps to guard against bank panics and other consequences should a country that never really belonged in the eurozone decide to drop out.
