I think Dubai has from oil production, at least on the surface. Much of its economy is in retail, tourism, construction, transport, IT and financial services, etc. Yes the initial capital came from oil, the bigger issues for them now are perhaps how much comes from debt and how much comes from neighbouring states if their oil economies collapse. Saudi is at the mercy of it's leader and little else. The culture isn't generally medieval but the Al Saud certainly can be.
