You're incapable of making a comment about anything without making a derogatory, racist remark about other nationalities.

Granted it could be argued that the Greeks are lazy and feckless but that is the way that they live their lives,
Greeks work pretty hard. Unfortunately they often fiddled their taxes, and many retired early on generous pensions. That was the cause of their problems, rather than being lazy and feckless.
The EU knew that Greece had cooked their books to join the EU and didn't care
That is an important point, the EU bureacrats should have known but they pushed through Greek membership, for reasons that we can but speculate on. It was irresponsible, and the Greeks deserve some sympathy.
