I don't think this is an accurate description of by-the-book 4e.
4e D&D awards XP on a "per encounter" basis, and awards gp and other treasure on a "parcels per level" basis. So as long as the players are participating in encounters and earning their XP, and hence their levels, they trigger the GM's job of placing treasure parcels. And with player-designed quests and player-authored "wish lists", the GM is not expected to be in sole control either of what the encounters are or of what the contents of the treasure parcels are.
So there is no expectation, in 4e, that the GM will influence player behaviour by the parcelling out of treasure (or of XP).
Again referring only to 4e D&D, I don't think what you say here conforms to the way the rules for XP and treasure are presented. What you describe here does seem, to me, to conform very closely to what 2nd ed AD&D presents. I don't know 3E or 5e well enough in this respect, but I wouldn't be surprised if it fits those versions also.
