It is up to you, believe in debt or not, Greece or not. The elites of Greece are putting the majority through to pay back a lie.
Smart nation-states (I say nation-states purposefully; not many of them left) like Obama's America or Japan just defer the issue.
Proof? Dealers (big private banks or firms like MF Global) take a loan from the central bank but without offering collateral. Then they loan out that money for a huge interest rate profit. But to get that loan, you must put up your home or business as collateral.
Meanwhile smart countries and smart banks take out more loans to pay back old loans.
