Simply don’t agree. Be well run, efficient, build well. Don’t just chuck money at issues.
If Moshiri had built well, we wouldn’t be in half of this mess.
That will certainly keep a club treading water... not being good enough to regularly break into the European places, but being good enough not to be drawn into relegation battles.
But, to regularly compete at the top, you need to be able to spend big money, both in terms of transfer fees and wages. The clubs which have this ability are ultimately going to be the ones who purchase the top players from these efficient, well built clubs. This both keeps them at the top while not allowing those below to catch up.
The rich clubs always have the 'get out of jail' card of being able to spend mega money on top players to plug any gaps. Everyone else is relying on a gem coming through the academy or taking a risk to buy a 'lesser' name, in the hope they will come good... and ultimately be sold on.
