Vic, you do realise that Economics is a philosophical subject and that you do not need a higher level of maths to study it, if that is what you are hinting at? It is why a lot of politicians take Philosophy, Politics and Economics (PPE) at university. If you can read you should be fine.
Or as Homer Simpson was wont to note: "The less stuff there is in your head is the more you can put in." Most MPs still have loads of space left.
