Minor league ballplayer making $50,000 > Pro golfer making $250,000
If you are on Tour and not yet good enough to have several sponsers, $ 250,000 will not go far. By the time they make the PGA tour, most golfers have their equipment at least provided by sponsers. But many still have to pay their own airfare and hotels, as well as food and maybe a car rental too. This gets very expensive for a 9 or 10 month season, not to mention if you also have a permanent residence to either pay rent or mortgage on. Golfers are at a stop from Wed thru Sun, paying for meals and hotel, and then need to travel to the next stop on tour.
Plus, each golfer either pays their caddie 10% of earnings or 7% plus the caddie's travel expenses. The bottom rung golfers' caddies usually choose 7% and expenses, as its a better deal for them. While Tiger or Phil's caddie would rather get 10% of their much bigger earnings and pay their own way. So the golfer barely qualifying for the tour has to pay both his and his caddie's travel expenses.
If you're a Triple-A player you get around $30 a day meal money, plus usually some kind of spread after the games, just not as good as the majors. All minor leaguers have their travel payed for by the team, sometimes plane sometimes bus, but never out of the player's pocket. Unless he misses the plane or bus and has to make his own arrangements. And hotels are also payed by the team.
