Isn't that essentially what happens with any business?
I agree there's plenty of parts and items that I can't get to grips with the costs of the items. But many times I still end up buying them.
I imagine that if we actually had the ability to see the overhead of some manufacturers, the costs may seem more justified. But obviously they also need to make money. Until I can produce my own stuff, I can't really complain as the choice is mine whether I purchase or not.
