Comparison of Eurozone - America

The Eurozone crisis seems like the perfect time to consider some of the differences between it and the United States:

US

• Central bank -- the Federal Reserve Bank -- goals are for "maximum employment, stable prices, and moderate long-term interest rates"'
• Single currency;
• Fiscal union that redistributes wealth, by way of stimulative investment and low-income / unemployed benefits;
• States must balance budget, no lending facility outside of capital bonds (but shortfalls in state budgets may be partially deflected by the fiscal union);
• Primacy of federal laws is immediate and absolute, even if contested and limitations delineated in a federal-level court (the Supreme Court of the United States);
• Single, official, national language (English).

Eurozone

• Central bank -- the European Central Ban -- goal is to "maintain price stability"
• Single currency;
• No fiscal union;
• Member states don't need to balance budgets as long as they can access long-term bond markets, but have signed the Maastricht Treaty whereby they agreed to limit deficits to 3% of GDP and debt to 60% of GDP;
• European Union-level laws hold primacy, but sovereignty rights creates conflict in cases of member states' Constitution;
• Multiple official languages.
