In my experience with Apple parts they are roughly in line with my expectations based on a) the price of the computer, and b) not being designed for any part to be replaced independently. These aren't great factors of course, but I'm not sure the problem is expensive parts.

I've usually found logic boards to be ~1/3-1/2 of the price of the machine, which considering they have the RAM/SSD soldered on, feels like ~1/3-1/2 of the value of the machine to me. Similarly, screens are often in the same sort of ballpark and I'd say that matches my expectations.

If you start from "how much does a motherboard cost" or "how much does a screen cost", that's going to miss a lot of the legit costs of additional components, higher quality components, or laptop form factor costing more.

Yeah, but if the only problem with your motherboard is a $3 IC that got fried and everything else is fine does it make sense to have to buy an entire new motherboard?
