What is the hourly rate of your Angel Investor and how much are you expecting?
684 is waaaaay higher than both the vanilla game and my mod. The normal hourly rate is 406 and with my mod the hourly rate is 471. With a 41% bonus from a Distinguished Economics Honors Degree, that would bring the rate up to only 664. Your Sim is doing quite well for themselves, and they either have a number of other bonuses already active, or benefits from a different mod.
