Money has always been the driver for which club is successful. Liverpool in the 70s, Man Utd in the 80s and 90s, Blackburn tried to do it in the 90s, Newcastle tried it too, even Woolwich in the 20s and 30s, Sunderland way back in the 40s and 50s, all had their on field fortunes changed by huge investment from their owners.
The difference now is that the wealth gap is larger, and the established teams hold more power to prevent another Man City/Chelsea situation.
For what it's worth, I don't want to do what Man City and Chelsea did. I want the club to be allowed to spend what it can afford,
within reason. I don't think we should be allowed to drop £1bn on transfers in January and another in the summer. I use Brighton as an example of a club who is handicapped by the current rules. They can't build a team around a few players because those stars will need to be sold and likely sold to the big PL clubs. So they strengthen the very teams they're trying to catch. The PSR rules need to be more in line with UEFA's FFP and it needs to be updated to take into account the rising transfer fees and wages.
ASM was the only player we sold to the Saudi league and it was in line with an objective website's market value.

If that was a route we could have used to raise significant funds, why didn't we ship off Ritchie, Fraser, Hendrick for more than they're worth? Why haven't we picked up Neves on loan or Benzema?
Newcastle are under more scrutiny than any other club when it comes to money coming into the club. There were rule changes to further scrutinise related parties sponsoring us for inflated fees, rule changes to prevent us getting players from related clubs for decreased fees. Which I get and it makes sense, it's a handbrake but it's fair in my opinion.
Oh... and our owners are scum.
