Those who are not wise to the thinking behind it are then grateful for this "gift" from the state,become convinced they are dependant upon the state for their financial wellbeing,and of course,will vote for the party who "gives them the most of their own money back - which they shouldnt have taken in the first place.
Its a clever way of continuing the job they have already completed on people on long term benefits.They become convinced that they cant survive (even in the boom years which have recently come to an end)without the state giving them other peoples money.
Then start on the people you are taking the money from - give them some of it back,and if they cant see the wood for the trees,they will be grateful.Gordon McRuin was many things (most of them not fit for OOF,s word sensor) but he wasnt stupid.
