Not a bad metric. Of course there's alot of ways to slice it, but if you compare the millionaire landlord of say low income housing vs the owner of high income housing - same income - people do look down on the 'slum lord'. Someone making $10m per year paying poverty wages (infer they are getting rich by paying poverty level wages) is going to be judged differently by people then the CEO paying $200k median.
