Will the Euro survives?

1. Why are Greece, Ireland, Italy, Portugal, and Spain sometimes referred to as the euros zones "peripheral countries"?

2. Why did the European commission bail out banks in Ireland and Greece? Why not let them default?

3. Investors demand that Portugal's José Socrates and other leaders make big spending cuts. However Socrates and other socialist prime ministers would prefer to generate economic growth via government, spending does this make Socrates, Zapatero, like minded leaders Keynesians? Or are they following Hayek's principles?

4. Why do citizens in France, Great Britain, and elsewhere stage protests when the government imposes austerity measures.
