The next logical step, although it may be politically controversial, would be to do the opposite of what the Tories suggest. Instead of reducing taxes on interest payments, the Government could tax all bank deposits and other risk-free savings. This would create a negative risk-free interest rate, encouraging savers either to invest in property, shares and other productive assets - or simply to save less and consume more. In either case, the result would be more consumption and physical investment, less unemployment and faster recovery from the slump.
