The Federal Reserve put in by Wilson, a democrat instead of a real central bank like every other nation is why the 2006 dollar is worth about 4 cents of a 1913 dollar.
Compared to 1913. the U.S. dollar has held up far better than the British pound, the French franc, the Itallan lira, the Portugese escudo, and the Japanese yen. (Assuming that the fixed conversion rates to the euro for the franc, lira, and escudo to the euro are used.)
Among European currencies, only the Swiss franc among can be said to have retained its value better in the period since 1913, so I fail to see how your dig about real central banks has any merit unless I misunderstood you and you meant to praise the Federal Reserve for not being one.
