Sorry, only just seen this.
I think they are (now) genuinely emotionally involved with the club - winning every week helps, of course. Whether they were in the beginning we will probably never know.
I'm merely saying that they are getting nearer and nearer to the glass ceiling. For Fleetwood it was League 1 , for Salford it seems it is League 2. I doubt that the current owners of Wrexham have the financial wherewithal to take them much further and if they do go up they are going to find themselves playing with quite a few clubs who are better supported and equipped than they are. Spending their way through that is probably beyond them - but we'll see.
I agree with you that - unlike Fleetwood and Salford - they are a club with significant history and potential. But the ground ISN'T bigger, and it will cost a hell of a lot to do anything about that. They could conceivably get 15k in different circumstances - equally, if things go wrong, support could fall back towards the 4k that they traditionally attract. It only gets harder for them from here, once they lose their spending advantage. It's nothing to do with jealousy. I'm just observing that they are heading for a bit of a conundrum.
As for Everton, I think you are paraphrasing what I said. My sympathy for them is entirely for their supporters ; the club itself is a complete dog's breakfast, and what you have at the moment is a mix of poor ownership, inept regulation and a potential external "partner" who might do the club irreparable harm if they get their hands on it.
