Never in history anywhere in the world has the policy of slashing both taxes and benefits actually produced an improvement in general economic well being! The problem is that slashing benefits deprives people who are so poor that they have to spend all their income immediately (with no capacity for savings at all) of some of their already inadequate income. This has the benefit of cutting costs to the exchequer but unfortunately tends to reduce economic activity because money has in effect been sucked out of the economy.
On the other hand, giving tax cuts to the rich doesn't promote economic activity as the rich are well-heeled enough not to need to spend such windfall funds immediately.
The stupid bitch has obviously read Adam Smith but not John Maynard Keynes!
