The Greeks are in trouble because of too little government interference in their economy? Because their taxes are too low?
I think we're in trouble because of bad public schools and poor reading skills (ahem).
Yes, in effect, the Greeks are in trouble because of insufficient tax revenue.
While the Greek tax *rates* are high, the level of compliance with their tax system is laughable. Everyone in Greece brags about how they’ve gamed the tax system to not pay taxes.
