Oh, I wouldn't put a Wealthy by level table player facing. But the problem now is, if a new DM uses the treasure tables of the DMG he will not know how much money the players will get approximately. They wouldn't even know that this is important, because the DMG has like nothing on spending all that money that is given out.
The 2024 DMG deserves at least a page on what to do with all the money the treasure tables doll out.
The DM put Velociraptors and disfranchised Orphans into the City! What else was my Wizard supposed to than build a Militia out of it?

My DM trough is into a Dungeon Delve right after so he can figure out how he wants to handle the Velociraptor Child Army.
But yeah, the DMG needs some general advice/guidelines on how to handle such stuff. I don't expect the DMG to give me price ranges for buying Velociraptors or wages for Orphans turned Militia Men.
But my actual point was: My Characters always find ways to use money. Because Money is Power. Even in D&D except for maybe the most ... uncivilised campaigns. It can be as simple as giving a guard a sure bribe of 1000 Gold (depending on the salary 3 to 30 years of wages) instead of charming or killing him or as complex as building and financing your own Militia and bribing the population to win a power struggle against a crime syndicate and a wizard academy.
Because for me Money is a tool and I will find ways to use that. Like the DM didn't plan for me to raise a Velociraptor-Orphan Cavalry. He just put in a fun Velociraptor Merchant I helped with the bureaucracy while waiting for the Bard to get his license to play on the streets and when the power struggle became clear I was like: Hey, Velociraptor Cavalry! So even if the DM doesn't plan Money Sinks into the game, I will give him some.
