It's also not solely about money, you can get far just knowing how to chum it up with Trump when you get in the room with him. Look at the odd quasi-bromance between him and Mamdani who you'd expect to be enemy #1 but Mamdani knows how to schmooze the exact type of New York Guy Trump is.
It's also potentially an implementation of the foot-in-the-door technique (https://www.simplypsychology.org/compliance.html). It's a common manipulative strategy where you get someone to do a small favor for you which makes them much more likely to do a large favor for you later.
