Greece refusing to reform is its own problem. Ireland played the good child and did as it was told after being bend over the EU's knee and got a grand old spanking.
Things have much improved there and probably be hitting full employment within the next few years. The EU has an approval rating of 70% now.
Greece can leave the EU and the Euro but in or out they will still have to pay back Europe.
That's a callous assessment of the situation. The Greek people did not deserve the treatment that they've received. Syriza mishandled the situation but that doesn't excuse the shortsightedness and cruelty of the EU institutions in dealing with the crisis, specifically in a situation where debt relief was so obviously necessary.
Things have improved in Ireland, but there was no reason that we should've had to pay back 3bn/year following the promissory notes. Ireland did not benefit from the promissory notes, but the Eurozone as a whole did through greater financial stability. Ireland has paid more than any other country towards the economic crisis.
It's this ridiculous attitude that where countries like Ireland are Greece are regarded as irresponsible, individual states when it comes to the Crisis, while ignoring that much of the crisis was manufactured by policies specifically promoted by Germany in Germany's own self-interest.
And things are looking terrible for Ireland if the EU takes a vindictive approach to Brexit negotiation, which it seems highly likely to do. Any international organisation that needs to impose terrible costs on both Member States and states that are leaving in order to maintain its own integrity isn't a worthwhile thing.
