It works in american sports bc there is no promotion or relegation. Can't work in a sport with it. I know the big bash has no more teams than the few that participate and cricket economic model is even worse.
American sports play under one federation. Who do you want enforcing the rules? Uefa? Fifa? The national fa? The national league? Other national sporting authorities? Other European sporting authorities? Other global sporting authorities?
Who's laws do they follow? National? Continental? International? Regional? How do you create an even field when some teams are getting UCL money and dominating local leagues?
Do you make man city give their UCL winnings tk Southampton? How do you account for the Italian tax system?
Again its not possible in football. Not that no financial law is possible, just that the salary cap won't work. Bc the revenue of teams can never be the same.
Barca can spend 40% of their revenue on sporting expenses and so can Cadiz. They just have different revenues.
How do Cadiz get the big revenue? Either outside investment like psg etc or long term European football (nearly impossible and only viable for a couple of clubs in every league).
So the uneven nature will exist so long as:
- Teams play in more than one competition.
- Promotion and relegation exist.
For the old money thing. All profit and the money of capitalists is exploited and the surplus value of labour of the workers. All investors are the same. They can't have money now if they aren't exploiting someone now.
But let's drop this argument, it never goesnto a natural conclusion.

Now I'm not an expert in these leagues. But i know a lil about the bbl atleast.
I predict the NRL has no relegation? And teams only play in the NRL? I also guess the worst team has first pick in drafts or whatever?
With the BBL, its ridiculous. One year your best players get called up to national teams and you're done for. Its a joke the way cricket leagues are run. Similarly no relegation.
