I think you and I are talking about very different types of match manipulation, incentives for such manipulation (i.e. protection and enhancement of the “product”, which leads to revenue generation), and who is orchestrating the manipulation.
And you are being incredibly naive if you think the UK top flight are the only top tier leagues in the world (and, more broadly, the only enterprises in the world) to be free of match manipulation. It has been proven to exist everywhere else where it is largely fractionally as lucrative to manipulate outcomes. This is a very exceptionalism view of football in the UK and one that I am sure the likes of the PL and FA would be very happy to hear you hold.
As far as the wiki entry you linked to and whilst it is very interesting, I would strongly argue that the sort of match manipulation I and others (including former officials and players) argue occurs the UK top flight—and, indeed, elsewhere—is at a completely different level to what is described there, protected by many, many layers of obfuscation, built up over decades, and incentivised via vast sums of money and power.
That’s the irony of corruption at higher levels: it does get more difficult to pull off due to much more stringent scrutiny, but it also becomes much easier to cover up for longer periods of time (though, not indefinitely) because of the more robust mechanisms that enable and hide it, often including the regulatory bodies meant to prevent it in the first place.
You have spoken about multi-millionaires being difficult to pay off to manipulate outcomes but that is based on a false premise that more money is used to coerce compliance and/or complicity, rather than the threat of less money or the use of blackmail (which can include threat of exposure of past misdeeds).
That is the case across industries and something I have quite a bit of professional experience with. Multi-millionaires are regularly coerced in to taking certain ethically dubious and/or illegal actions based on the threat of loss of wealth, reputation, life, or all of the above.
Some would argue blackmail is actually easier with the wealthy because of the nature of their lives and the complexity inherent in the structure of their wealth (I.e. more often than not, there are many more people threatened by one person’s dubious history being exposed than would be the case we a less wealthy person, which strengthens the power of coercion). These are simple, discrete manipulation schemes. Many people stand to lose quite a lot, from the top to the bottom, by having them exposed.
But the truth usually comes out eventually, as we have seen before in England, Italy, Spain, Portugal, America, China, and elsewhere.
All of this is to say: from a professional perspective, after years of working in the financial data analytics and fraud prevention sector, I think you are being exceedingly naive with your assessment.
