It seems as though you underestimate the appeal of billions of dollars. It's not just the ability to never have to work again. Or power, prestige or any other nonsense. Or even just having tons of money. It's not greed that makes it appealing.
It's the security. The safety if knowing you'll never have to worry about food or housing. That your parents and family will be well taken care of. Your children will be able to have it all, that you've set them up for success and they won't have to struggle. It's knowing that your best friend who was diagnosed with cancer will have the best care available, wherever that may be in the world, and won't have to worry about food or housing or anything else while getting better.
You're either too young to understand or are lacking in empathy.
I'm not saying being a billionaire isn't inherently immoral. But the reason people take payouts like that are not solely down to greed.
You know I don't work with fractions of an inch on a daily basis... Or even monthly. But inevitably a couple times a year it's relevant. Every single time I have to take 3/4 multiply it by 2 and get 6/8, then I have to subtract 1/8 to get to 5/8. Repeat ad nauseum to get to whatever time fraction is needed.
It's frustrating and slow and makes me feel dumb.
That said last time I did it, I measured a 1/8th difference between cabinets we ordered from IKEA and the space they went in and I'll tell you what, I felt like a genius when it all just fit, perfectly.
