The assumption that all fat cats are big spenders on everything is a miscue.
You can't paint the whole lot of them the same color. In my line of work, I have heard from some who tell me that their accountant demands that they spend more money. Well... one... she told me that he had to spend the money in her actual expense account by the end of the month. She would take my wife and a few of her friends to buy them almost a complete wardrobe occasionally. Or, buy a lot of my work. I don't know how that works, because I'm not exactly that rich, ha ha.
But, if I had an accountant demanding that I spend several thousand a month, I'd be getting creative with it... making youtubes of me juggling Eltangs while riding my unicycle through a bed of hot coals.
