If self sufficiency isn’t sustainable, what is? Burning money?
But it has to actually be self-sufficient to be sustainable. Merely buying a cheaper thing is not inherently more economically sensible if the cheaper thing is useless. I refer you to that seminal economic tract, the Samuel Vimes Theory of Boots:
Take boots, for example. He earned thirty-eight dollars a month plus allowances. A really good pair of leather boots cost fifty dollars. But an affordable pair of boots, which were sort of OK for a season or two and then leaked like hell when the cardboard gave out, cost about ten dollars. Those were the kind of boots Vimes always bought, and wore until the soles were so thin that he could tell where he was in Ankh-Morpork on a foggy night by the feel of the cobbles.
But the thing was that good boots lasted for years and years. A man who could afford fifty dollars had a pair of boots that’d still be keeping his feet dry in ten years’ time, while the poor man who could only afford cheap boots would have spent a hundred dollars on boots in the same time and would still have wet feet.
If you buy 'cheap' players that are not very good and which you need to replace after a year, that is not actually sustainable. If you buy good players who can either do fun football things or be sold for large amounts of money in order to afford other good players, that is sustainable.
That's obviously reductive in that there is no guarantee that an expensive player is better than a cheap one. But wages tend to cluster; your £10m transfer from a lesser league probably isn't on that much less than your £20m transfer, and the odds of your £20m transfer coming good are (if you have any clue what you are doing whatsoever) better. Meanwhile, when you have a bunch of £10m transfers all of whom are making wages that exceed those paid by all but 30 clubs in the world, they tend to accumulate. It's far harder to undo those mistakes, even at a moderate loss.
Thus, how we have a rather unusual situation: our pay scale is such that we have difficulty acquiring high-end talent, while our payroll is also obscenely bloated. Because instead of paying a few good players a lot of money, we pay a bunch of soggy cardboard a fair amount of money. Being cheap is really expensive.
