Simple,,set the dole money at £5 a day in money and the same in food vouchers, for the first six months then it is lowered, each six months until no actual money is paid out.
Stop any payments to non uk residents, make people on incapacity benefit sign on like everyone else claiming benefits also randon visits to incapacity claimants and on the spot medical tests,,no benefits to be paid to non uk nationals unless they have paid uk taxes for at least three years.
The simple thing is,,people will work if you force them.
