A widely accepted axiom is that parity in sport is generally beneficial, and something that governing bodies should always be striving to increase.
It’s no coincidence that the three most profitable sports leagues in the world — all based in the United States — use a combination of salary caps, luxury taxes and talent drafts to ensure competitiveness throughout their seasons, and prevent the kind of lopsided results common in countries with more capitalist sporting structures.
Sport, at its heart, is entertainment. To retain fan interest, not only must competition be of an elite athletic level, but it also has to have an element of unpredictability.
