Interesting charts in today's Wall St. Journal. It shows US exports to Europe to be only 1.2% of US GNP. That means the entire continent could disappear from the face of the earth and we would only loose 1.2% of GNP in export sales. To be real, Europe won't disappear completely, worst that can happen is it drops into recession and it's US imports drop off somewhat.
Somewhat larger, Eurozone banks make loans to the US equal to 10.5% of US GNP. If things get bad enough in Europe, and enough Eurozone banks fail, that lending can dry up. But so what? We have plenty of banks over here, and we can print as much money as well like to fund loans.
In short, a Euro meltdown won't hurt us nearly as much as it hurts the Europeans. Of course plenty of US politicians are already pointing fingers at Europe to explain miserable US growth rates. How can you tell when a politician is lying to you? When you see his lips moving.
