While I despise apple for a lot of reasons, I have to somewhat defend them here. MacOS is a lot more efficient with its tailor made hardware and 8GB of RAM in a MacBook is closer to 16GB in a normal laptop. Their hardware prices are around the industry standard if you look at the windows/android equivalent of their advertised specs.
Of course the flagship products are completely overpriced, but that's the case for pretty much all manufacturers and not really what should be looked at for comparisons.
