°The five marks of the Roman decaying culture:
- Concern with displaying affluence instead of building wealth;
- Obsession with sex and perversions of sex;
- Art becomes freakish and sensationalistic instead of creative and original;
- Widening disparity between very rich and very poor;
- Increased demand to live off the state.
[ Edward Gibbon, The Decline and Fall of the Roman Empire]
