It's a matter of time and place. The celts, the goths, and the Scythians were aryans with a warrior culture going back thousands of years. But the Roman people lost their warrior culture to a professional army replacing them, and bread and circuses placating them. The peasants that the goths took over were no longer warriors, and the trend has been the more a land develops the softer the people get. By length of time and generations, we've been warriors many many times longer than civilized semi-slaves. But by population count there's probably been more of us in the latter category, or at least close to even.
