The PL is essentially the member clubs themselves, albeit operated as a separate company (owned by the member clubs).
In theory each club has an equal say, but there are most likely some clubs with more political and financial clout than others when it comes to exerting influence. That influence must be nigh on impossible to police as much of it may occur away from the PL itself and behind closed doors of specific cliques.
We ourselves got into such a situation with the European Super League, where it was clear we had collaborated with other clubs in a clandestine manner.
The PL probably falls into three groups. The established big boys (Liverpool, United, Arsenal, Spuds...), those aspiring to compete with the big boys on and off the pitch (City, Villa, Chelsea,Newcastle, Everton) and those who probably don't anticipate competing financially but just want to be able compete on the pitch... (most other clubs).
That list is very subjective, but in the right ballpark on most fans eyes. Many will now have City and Chelsea down as part of the big boys they choose to despise.
The established elite really don't want competition.
Those that feel they can't compete financially don't want the gap to widen and would prefer curbs to the spending.
It's only those with a realistic prospect of trying to repeat City and Chelsea's fortunes that are likely to side with us. So we're probably outnumbered 2-1 at the very least.
Can we really be surprised therefore that the PL acts as it does?
