How does "unlimited' class have rules?

Seriously though, classes have "class associations" that set conditions for competitions. There is politics involved in all situations where people are involved. It appears that David Rose came up with a revolutionary idea that would have made everyone else's investment worthless, so they "ruled" his idea illegal to protect their investments. Same thing happened after the 1967 Indy 500, although that is not an "unlimited" event, they changed the rules because Andy Granatelliu out smarted everyone.

Same concept is keeping us from breakthrough technology to solve the worlds energy, starvation, pandemic, you name it, problems,

I forgot about that scene in Butch Cassidy I'm going to watch that again.

Yep money in the pockets of rich people is what makes the world go around. As long as it gets back into the same pockets with an increase.

Pretty sad when so many people work so hard for so little gain.

Unfortunately there are no simple amenable answers. To many people would not like a leveling of the playing field.
