Part of the reason is that Apple & Google don't charge credit card processing fees. So for a $1 app, 30% is ~ their cost. Of course, that logic doesn't scale to things like $9.99/mo subscriptions and the like.
Apple could take out credit card processing fees and then charge 5%, but up until now they haven't had a reason to change. Perhaps we will see change here, who knows?
