Yes, and look at the Greeks now.
Greeks now are disgusting.

My guess is that, during the time of the Roman Empire, the most talented Greeks migrated to where their talents fetched the highest price -- Rome. Modern-day Greece is comprised of those who stayed behind.
This was how the US became so great -- we were the magnet for the most talented people around the world. Now, we are a magnet for every shiftless loser who wants a piece of our welfare system.
