Do I have to spell it out?
Greece joined the EU back when, with an expressed condition that they meet some target of book-keeping nationally.
They made it by the skin of their furry teeth.
Except they didn't. The books were cooked. That's a matter of record.
They've lived the high life for the last several years; they're bust. No money. Skint.
They were a while back & they are now.
They were bailed out then to the tune of 100BILLION.
Now they need another 100BILLION.
Where's that coming from? There is no magic money tree at the top of mount Olympus.
Taxes. Not Greek taxes, either - that's not how a bale out goes.
The EU / EEC is another story. Look to its birth - fathered by German repentance and work ethic, mothered by the French ... farmers, who have done splendidly out of it, les petits whatevers.
It's a mess unless you're a banker or a politician or used to be a French farmer!
Remain cheerful, though as it doesn't last much longer.
