But the morals of a society are not constant. They are a function of the morals of the individuals living in a society. What was perfectly acceptable in the 12th century is barbaric now. In a century or two we will seem barbarians to our descendants. (And they will still be saying that their generation lost all morals and humans will soon die out.)
Irak, the SUV vehicles, the bullying in schools, people parasiting the welfare system, the predatory banking practices, all those things seem barbaric to me.
Iraq: seems short-sighted to me. We don't tend to judge past civilisations based on one war.
SUVs: maybe, but I would say our continued reliance on oil in general rather than SUVs in particular.
Bullying: could be.
Parasites on the welfare system: not convinced. The fact we have a welfare system will be judged favourably I expect.
Predatory banking practices: pass, not sure.
It's hard to imagine what things it will be--their values may be very different from ours. I'd say oil reliance, over population, the gulf between the rich and the impoverished, but these things are all too obvious. I suspect we'd be surprised by what we're judged badly for.
