Cause and effect, reap what you sow, law of karma -- all amount to the same thing. I have been at least vaguely aware since the age of about 15, that as a wealthy world power, we run the risk of the fate of the Roman Empire. I am in agreement with you that moral absolutes must be upheld. The Germanic peoples practiced a Spartan self-discipline, for they lived close to the land, where nature is unforgiving.
Selfish over-indulgence and apathy about injustice to others are the great sins of dissolution that ruined the Roman Empire. Jaded appetites and vacant consciences. Let's not let it happen here!
I misunderstood your post... not being too lucid on the finer points of Roman and German history. My apologies.
