Certainly in western/Christian culture greed was traditionally been seen as a sin, not a virtue[1]. I'm not sure how much this applies in other cultures. Perhaps you could cite some examples?
[1]Not that this stopped the clergy being greedy of course. The grossly overweight priest is very old trope.
You are citing some dickheads with Ferraris as evidence that greed is a virtue now but disregarding the fact that people had similar gross displays of wealth in the past as evidence of the same.
However there is a difference in being seen as virtuous and actually being virtuous.
Few men reach a point of actual virtue in private and secret life. Many more men cleverly signal virtue in their public life yet retreat to vice in private and secret life.
The back bone required to actually be virtuous must be strong enough to stand against any wind in the event all laws of man were laid flat.
True virtue (I assume and make no claim to having it here) may possibly only exist in doing the right thing while answering to no authority while serving no system and while receiving no recognition or comfort of a superiors approval.
