We won a bunch of medals in stupid X-style "sports" that we invented. If it wasn't for those, we would have been buried by Latvia (or similar).
4 or 8 years from now, the countries that can afford to coddle its children to do crap-sport stuff will start edging us, just like we have lost the edge in Basketball.
Does it seem to you as if those snowboard events are just a little bit too easy compared to the work, long hours, and years of dedication that other sports require?
Then there is the money thing. Compare the cost of fielding a bobsled team entry with that of a snowboarder.
I'm sure glad we invented it, though. Gets us medals with very little effort.
