Sport is very different than other businesses. It can lure in lifetime "subscriber" as well as momentum glory hunter. Business need to improve their product. Sport is dynamic in itself. Players' style may be alike but they are not the same, tactic may just build on older tactic & nothing really improve; but the play is different.
It may be in entertainment industry but it's a multiplayer game, so there is no script. There may be trend but the unexpected happen. Like it or not the lifetime subscriber stay while new hype & trend draw in new followers. And as I stated in previous my previous post, football marketing side is underdeveloped compare to how American in house sport being marketing. The room for growth is huge.
Value if you narrow it down to player quality then there shouldn't be much price high in football history at all. I meant the average class product should never price should never overcome the previous premium class even with time. A limited edition car with time still hold great value while the regular car would end up in grave. How average players in later generation keep getting more experience than previous generations' world record. As explained above, people love changes. Even the average players are not as good as previous great, they're different & draw momentum hype to keep the subscriber & draw in new followers. The point is the average will get more appreciation (in value) with time, as sport business grow. Buying a house/ renting a place you would look at your income/ job. Sometimes the bubble grows that it's not affordable compare to the wage thus result in correction. Does sport, in this case work the same? If you can't afford to live in Manchester, and travel with the team, you pay for TV deal to watch games. Read newspaper (quite some bullshitter make good living out of it) The team need to keep the pulling power, they need to stay competitive, so the team need to change. Staying out of it & wait for a correction & while not seeing it as different beast is in itself is a flaw, whoever subscribe to that line of thought.
Let me ask you few questions: What if football transfer market bubble burst? Will Ronaldo, Messi suddenly become available? What is their correct value? Will players in their same mold suddenly appear more?
