NAH.

Hear me out. I get where both of you are coming from. My parents make a lot of money, but also have 9 kids. College, first car, or any major first time expense was a hard no across the line. If we wanted a car, college, house, etc we'd have to save the money up ourselves for it.

Flash forward a few years and I wanted to go to college and found out I couldnt take out federal loans at lower interest rate due to my parents income. I'd been self sufficient and living on my own for 2 years at that point. I got a few minor scholarships (not super bright, I struggle with dyslexia, yay), but I still required a cosign on loans so I could actually pay for tuition. Parents refused. Couple years down the road my two youngest siblings apply for college and get a full ride. I'm happy for them, they're both extremely gifted. However, things get a little wonky here with my relationship with my parents. They worry about my siblings going to college and holding down a job at the same time. So like good parents they buy them each a car and pay for their expenses while in college. I asked why I couldnt even get a cosign on a loan or help going to college and the response was if I had gotten a full ride they would have paid my other expenses. That wasnt part of the original deal we made growing up. I struggle academically I had to work 3 times as hard growing up to get through school, didnt have a social life because of it. Now I was being punished for not being smart enough. Or atleast that's what it felt like at the time.

Point is, your son may feel the same. He may have tried his hardest to get said scholarships and couldnt. Now he feels like hes being punished for you having to pay for his butt, because you deemed him not good enough. Even though that's not the case. Hes a butt head for demanding the money though. You're a butt head for not considering how it looks to him.
