The essence of sport is equality - equality of chance, equality of opportunity, equality of eligibility, equality of regulation and equal competition. Remove equality from the equation, and the entire spirit of sport is destroyed - namely going further, higher, faster than the rest under equal conditions
There will, of course, always be differences, but sporting regulations exist to ensure that equality exists, and it cannot be coincidental that deleting "e" from "equality" leaves "quality" - and those are the two essential ingredients every global sport should embrace. Remove equality from competition, and it is reduced to handicap racing.
In all walks of life parties are remunerated at different levels, and that applies equally in sport: Roger Federer may earn more (or less) than Novak Djokovic over a year, or one member of a football team earn more than a team-mate, but in tennis sports fiscal power does not influence sporting power - whereas in F1 an advantage of up to $50m equates to an enormous difference in lap times.
