Wealth is a precondition, but not a guarantee. Big difference. At the start of your exegesis you maintained that wealth equalled success, which is clearly not so.Even in your post above you say "financial advantage and therefore football advantage". There is your non sequitur. Despite your shift you are still conflating the differing effects of ffp, the PL model, management activity and so much more. To analyse what works and what doesn't, you have to disaggregate all the factors and not assume a straight line of cause and effect. It is a polynomial. Good luck with that one.
If it were as simple as you suggest, everybody would be doing the same thing, with their competence at it the only difference between success and failure.
Have a look at Brentford's strategy, it is quite different from most and incredibly successful. Google Brentford Moneyball Policy or similar, I know there are articles on it
