The food supply is essentially infinite in cultures where obesity is a problem; wealth is essentially infinite for those who cannot spend it all in their lifetime; and time is infinite for those who waste it.  Increases in those situations are meaningless.  Some scoff at primitive numbering systems that quickly reach infinity rather than using large numbers, but that can be an effective way of thinking about quantities larger than what is meaningful.  Also, infinity reinforces the primacy of the future (which is infinite) over the past (which is merely finite).
