The world is printing fiat currency like crazy, to try to create growth while massive global debts are increasing. The U.S keeps printing money and increasing its debt to now pass 14 trillion. One of the only ways to protect yourself is to own some gold or silver.
In times of distress where the economy is suffering, people are heavily in debt and do not have employment what tends to happen is people start looking to blame another group of people within their country.
In the 1930’s in Germany they blamed the Jews, and now in Greece the greeks are blaming immigrants, instead of looking at blaming their leaders that got them into the economic mess.
