Do the pros still live off of wakeboarding?

I havent followed PWT in years, but I saw a "day in the life" short of Harley Clifford this week and it got me thinking about wakeboarding as a career path in the past and present. Can the guys live well off of riding anymore since the decline in popularity? Did they ever live well even during the 2000's? I always figured since the pros shared houses that wakeboarding was more for the life experiences while you're young and able, but seeing Harley's crib and considering he's not at the top of the game anymore got me thinking about how well these guys were able to do financially then and now.
