Is it though?
Even super wealthy people lose out when the commons is under funded. So a rich woman with cancer can build her hospital a new wing and get great treatment. (I know a lady who did that. She still died of cancer). If her housekeepers, chef, gardeners, fitness, instructors, & manicurists had access to the same treatments, there would be more doctors practicing these things & gathering data. The quality of her care would go up too.
