Thomas More said this quote

...if pride, that plague of human nature, that source of so much misery, did not hinder it; for this vice does not measure happiness so much by its own conveniences, as by the misery of others; and would not be satisfied with being thought a goddess, if none were left that were miserable, over whom she might insult. Pride thinks its own happiness shines the brighter, by comparing it with the misfortunes of other persons; that by displaying its own wealth they may feel their poverty the more sensibly.
