Marc,
As usual, you are imperfectly informed, not to say malicious.
However, you may assume some "envy" within the grunt ranks as we wish we had the sugar daddys that these top competitors must have to managed to be at every major event around the world.
Can you provide a shred of evidence to support this assertion? Most of these competitors accept a degree of hardship to compete and must have remarkable support from their families. For a start, I suggest you might have a quiet talk with Colin Campbell and his wife Susan. It may be before your time, but Colin Campbell was the MAAC President about 5 years ago. Or you could talk to Arend Borst, our last World Champion.
I do know of one FAI competitor who had financial support from an uncle, but only one.
