I suppose it's too optimistic to think they'll actually cut on unnecessary expenditures?
Like Nkandla, trains that aren't suitable for our tracks, golden handshakes, bonuses where they're not deserved (looking at you, ESKOM), to name just a few.
Cut all the international "fact finding missions" and other ministerial trips that aren't essential. Couple that with aiming to increase GDP and you could probably lower VAT.
