Whilst Greece is most certainly in a dreadful state the article is shockingly biased, as you'd expect from the Daily Heil.

I stopped reading after it stated that all Greece's problems started after they joined the EU.

Their problem of always living beyond their means precedes their joining of the EU and Euro.

The mistake was allowing them to join the Euro whilst their economy was in such a state.

We're not in the Euro and never will be so the comparison is ludicrous.
