Maybe peace is overrated?

There is certainly a price to pay for greatness, and some are willing to give it a shot. It seems so condescending to look down on poor them, not knowing peace when perhaps that is not the thing they are searching for.

My question was "Do they know any peace?"

Possibly they do.

It's not known to me either way.

Clearly I'm skeptical of whether materialism can deliver peace, and clearly I'm saying peace is worthy of pursuit, but falling just short of judging others' level of peace achieved is prudent.

Agreed. This purely materialistic definition of success is a very western concept.

Eastern traditions have gone beyond them a long time ago since they are much older.

Western traditions will eventually catch up.
