yes, for simple minds who have studied economics the future may look so easy.
1. The debt of the already bancrupt states will remain. If in euro or their national currency doesn´t matter.
If the euro should fail, Italia & Spain & France & UK are forced to file for bancruptcy within the following hour with Germany the big winner from this situation.
All investors will then take their money to Deutschland
2. the next 15years products Germany does manufacture are very much demanded by India, China and Brasil.
price does not matter. Porsche will sell most of its cars in China this year
3. With the skrinking population in Germany it does not need to feed new human beings.
Whereas other countries with higher birth rates will have deep troubles in giving every new member of society work, housing, education.
I´d say that 3/4 of the EU countries and the USA are already failed states because of their irresponsible debt policy where the criminal rich have occupied and destroyed the state, society and will leave as legacy completely ruined states.
