Of course there is:
Given politicians that know not only what their primary objective should be but that also hold the concepts of fiduciary duty and collective conscience in high regard, there are alternatives. EU membership or monetary union are neither essential nor are they the only way a country and society can survive. Is a union desirable? Absolutely. Is a union designed and implemented as the EU has been desirable? Absolutely not. Similarly, banks are not the one and only pillar of society. In a modern and open economy governed by the rule of law, banks are nothing but another business and should be left to go bankrupt when their business model fails.
But who are we kidding right?
