The thing is, the fans aren't killing them for not spending, they're killing them for doing absolutely nothing. Last year with Reyes, with that joke of an offer their was no reason to keep him. He should have been traded for prospects instead they got sandwich picks. Or this season, Scott Harriston should be playing for someone else right now. Even if you only would have gotten Wilpon wanted to try and sell Reyes's chase for a batting crown. With next years All Star game the same thing that happened with Reyes will happen to Wright and possibly dikkey. If the rumor is true about payroll not going up next season it's highly doubtful Wright and dikkey sign extensions this winter. And I'm willing to put my account on the line that if Wright and dikkey hit the open market they're gone, the Mets won't match whatever offer is out there.
As for the kids, outside Harvey and Wheeler the farm has some pitchers with upside but question marks. We overrate the rest of the system. We also have zero impact bats in the system. And to put things into perspective of how prospects are a crap shoot and Mets fans overrate the current system, in 1995 the Mets had 7 players in Baseball America's top 100 prospects, 6 of which were in the top 37. And it still took a few more years before the team became competitive again. And out of those 7 only 2 (Fonzie and Ordonez) actually had a meaningful impact on that team. Even in the 80's it was a bunch of highly touted young kids that improved the team, not just 2 and a bunch of question marks. The Wilpon's are trying to pass off Wheeler and Harvey as saviors of this franchise yet in the system after them are questions marks with upside and nothing. Mets fans won't be eating good for the next 2-3 seasons.
