Greece's debt problem seems to get bigger and bigger.

The rescue package for Greece just seems to get bigger and bigger from the initial Euro $40b and then upped to $110b and upped to $140b over the last few days. This just goes to show that Greece is hiding massive debts from the EU members.  Furthermore, EU has to setup a massive emergency fund to defend euro.  What happens if Spain or Portugal also collapses?  How is EU going to find money to help its member?
