The resignations of Greek Prime Minister George Papandreou and Italian Prime Minister Silvio Berlusconi have highlighted how Greece, Italy and many other countries obscured for too long their bloated public sectors' long-standing problems with unsustainable social-welfare benefits.

Governments have promised too much, to too many, for too long.
This fundamental problem has now manifested itself in these countries' unsustainable debt dynamics. Euro membership, which temporarily enabled massive borrowing at low interest rates, merely aggravated it.
