Each summer, there is a pot of money. We can spend some on agent's fees, some on transfer fees, and some on wages.
We could spend a bit less on transfer fees and give players bigger wages, but we strive to do the opposite; get good deals on transfer fees and don't overpay on wages, keep the basic wage fairly low and then reward good players with better deals and payouts if we achieve results (cup wins, high league positions, qualification for CL etc).
That is a perfectly good and normal way to run the business.
If Spurs was really poorly run we would scrimp on transfer fees and pay lots on wages and the wage to turnover % would increase. That is a bad idea.
Behind all of this, note that our turnover has doubled in recent* years whereas clubs like WHU, AST, NEW have seen a small increase. Thus their wages to turnover ratio has rocketed because wages go up but turnover hasn't. Spurs should be applauded for the increase in revenues, it does not mean we did something wrong.
What you're REALLY arguing about is the number of high earners i.e. those Twitter posts saying that ARS have a bunch of players on high wages, so do LIV, so do all the big clubs, whereas Spurs don't have many on high wages (e.g. over £100kpw) and we should have more.
That happened because we got rid of Kane/Son/Werner et al and recruited lots of kids on lower wages. As they develop and prove themselves, their wages will rise.
Yes, we could sign someone for cheap and give them a really high wage to attract them e.g. El Khannous but then why would we give them a high wage if we don't need to? Or perhaps someone like Osimhen which is probably where you are heading towards, we could get Osimhen for a relatively low fee and pay him a lot. Ditto Alvaro Morata, I think that is probably what you are driving towards??
