If spending lots of money to win a Cat 3 race and knowing you did it with money and equipment instead of fitness and smarts is OK with you more power to you. But if it means thousands of dollars spent on a race that likely paid < $50 to the winner the whole thing can also look ridiculous too depending on perspective.

This isn't really funny, it's a fundamental problem with cycling as a sport that limits who participates in the sport and hurts the sports ability to find and develop the best riders. It seems particularly bad in the US. Rules which helped control the equipment arms race would be good for the sport at the competitive level. Many promising athletes never try the sport because the costs are so prohibitive. On top of that in road racing if expensive equipment raises the speed of everyone in the field it accomplishes nothing other than increasing the risk of severe injury as speeds go up.

If someone made $10k shoes that gave a competitive advantage in soccer or basketball, or a $10k baseball bat that offered significant advantages, etc.. that equipment would very likely be outlawed right away. Cycling has let everything get very out of control. Baseball obviously has already banned lots of bats that offer competitive advantage, whether it's banning metal bats after a certain level or limiting the power of metal bats below that level.
