Manager's wage and transfer offer from AI clubs

[FM Noob]

I think that the wage system for a manager is absurd. I've won the EPL, FA Cup, League Cup, Champions League and World Club Championship with QPR over the years. Yes with QPR!!! And yet when my contract is almost up, they offer me a pathetic sum of not more than 20k a week to stay with them. They will not even oblige on a 1k increase when I tried negotiating with them. So I decided to resign after my contract ended and guess what.....the next manager that they signed was being paid 80k a week whom got sack 2 years later. Same goes for a transfer offer of my players. For example my player A is valued at 20 mil but they only offer me like 4-5 mil plus other add ons but they have no problem spending 70-80 mil on players from other AI teams. This seriously is absurd.
