frankly I don't like this diary. Any country has it plusses and minuses. And the Anglo-SAxons are not worse than others

and I am French and proud of it...

Any idiot can face a crisis - it's day to day living that wears you out.

Countries ranked by my hatred of them:

USA
England
all of Africa
most of central Asia
..
nearly all of latin America

Which made Capitalism possible.

(Accidentally) The Limited Liability Partnership

Which allows us to fix it.
