I believe the "platitude" is in all senses practical in that assigning worth is only easy and fully accurate posthumously. Also, no person is so one-dimension

I believe the "platitude" is in all senses practical in that assigning worth is only easy and fully accurate posthumously. Also, no person is so one-dimensional that they can be accurately summed up by the singular adjectives "stupid", "talentless", or "lazy" -- that's just not a realistic situation. A lot of famous people throughout history were in fact poor bums on the street, and are now held in very high regard by all social classes (perhaps it can even be argued that the elite place more worth on them than the lower classes, ironically).
