A thought that seems relevant in this context: How much money does an individual need before getting more becomes effectively meaningless?
Most of the top players could retire today, never work another day in their life and have the financial resources to live very comfortably. Even mid-level tour players make life-changing amounts of money - for example, Kevin Na has been on Tour for quite a few years, winning a few tournaments but never really being one of the best players at any time, and he's earned more than $35m in prize money. Yes, there are significant expenses involved in playing on tour, but he'll also have sponsorship money coming in. Na won't be getting anything like the 9-figure sums that are reported as being paid to some of the bigger names to sign up with LIV, but it's likely that he'll have received something of the order of at least a couple of good years of Tour earnings, with any prize money in addition to this - a significant amount of money, yes, but does it make any practical difference to the life that he leads?
