In my original post I removed a whole section of how it might affect lower league teams. For example, let's take the 3 PL teams that get relegated in an era of low PL prices. Yes, they get massive parachute payments, but unless they behave sensibly and/or return to the PL quickly they may actually have to raise their ticket prices in the short to medium term while they adjust their costs. That wouldn't sit well with supporters. But I would suggest that prices are set by the PL and gratefully followed by the lower leagues because they need the income much more from tickets, which is the point you are making. The thing is, there is massive headroom for the PL to drop its ticket prices without squeezing the lower leagues. When we see Arsenal's pricing as high as £97.50 for a single ticket and Chelsea's cheapest at £59, there's room to manoeuvre. Leicester City's cheapest is £22. Not bad at all in the current era.
When we see surveys of the cost of watching football in the UK, no matter how rigorous it seems the survey is, there are always different costs within Europe. I would like to see one which takes two or three typical clubs, or maybe a truly representative average of a particular league, and tease out all the costs and revenue, right down to the rent and rates the average club has to pay because, on the surface it looks like the UK clubs, especially the PL ones, are making a small fortune out of their captive audience, who won't rock the boat because that would be disloyal. Well loyalty works both ways.
I see it as Human nature to say this is a Matsui. I am not paying a Sony price for it. This is a Kia I am not paying a Mercedes price for it.
I have heard many people for years, maybe more than a decade say things like (using today's prices) How much? For L2/Conf football. Why would anyone pay £16 to go and see perceived "****" football at Lincoln when many PL tickets are a tenner more and as you say with Leicester only a little more.
It isn't about the reality of the purists idea of quality. It doesn't matter that in reality there isn't that much difference in quality between a Pulis West Brom and a good conference football playing side bar the abilities of the players. Some good football played by many lower league clubs and as they are on a level playing field so to speak with the teams they are playing then it makes for a good game most of the time.
However get away from the purist idea most people take the Sony / Matsui or Kia/Mercedes scenario. If the PL tickets reduced to £20 lots more people would be assuming that the prices in lower league football should come down too. They would not pay the same or nearly the same for the tickets. When Lincoln get a big team in a cup (not happened for a while) but remembering back we had Sunderland, Everton, Palace a few years ago the part timers that suddenly fill the ground for the 'big game' are amazed at the ticket prices and their comments show that they think the club is taking advantage of the situation and raising the prices because they are playing a big team. The truth is the prices are the same but these people do not realise that.
Lower league clubs suffer more than higher attended clubs. The more money a club gets the lower the ratio of the actual overheads (not including player wages.) The maintenance, the energy costs, policing, staffing etc. all much a higher ratio of the take in money when you are getting 3,000 attendance which when concessions are taken into account will probably mean takings of £35-£40k for a match. Eastleigh are in the same league and their average is half Lincoln's.
It might be different for some clubs in the lower leagues that get much bigger attendances like we, Man City, Leeds did in L1 and The Sheffields and their like enjoy but for small clubs with just a few thousand it will be a killer.
If the PL tickets come down to £20, lower league attendances will fall just because people will perceive that they are being ripped off.
PL tickets do need to come down but at the same time the PL has got to start doing more for its pyramid as well. More money HAS to come back down the line. Forget football fans saying that footballerºs wages are crazy. One week of Wayne Rooneyºs wages would keep a club like Lincoln or Eastleigh alive for a year.
