Well, I'm an American citizen, and spent my first 18 years of life in Germany, so perhaps I could shead some light on this pseudo-intelectual BS.
Slavery not only implies forced labor, but an absolute requirement to perform such labor and to conduct one's economic activities so that funds are retained within a country's economy. So, the fact that I could work in a German pizzaria for a few years, pay german tax dollars, and be very dependent on the german economy AS AN AMERICAN CITIZEN without getting shot in the head by a CIA agent goes to disprove your concept. However, if I were a russian during the Soviet years and I worked in west germany on my own will, I'd likely have some problems to face if I returned home to Russia. I am free of that as an American.
But hey, think what you want, as an American, I'm willing to uphold your right to think that we are slaves
