Regarding Andrew Parsons' letter (Letters, September 27), lowering wages drastically worsened the Great Depression. JM Keynes pointed this out when positing increasing aggregate demand as a far better policy for protecting employment and output levels. Keynes argued that lowering wages would lead to lower output prices, further depressing investment, employment and GDP.

Tax deduction
Patrick Deane (Letters, September 27) suggests removal of tax deduction on interest expense on rental property. Landlords contribute no net benefit to the economy unless they buy new builds. Then whether a house is rented or owned by the occupier makes nil difference to the total number of housing units available. Any landlord who owns a property outright would be no worse off under such a law. Longer term, reduced competition would lead to stable property prices and lower housing costs for buyer occupiers. Indirectly capital would be freed up for investment in productive enterprise and collectively New Zealanders would own more of those enterprises thereby contributing to increases in productivity.
Also one has to ask why a borrower should benefit personally from the use of money which they have made no effort to create. Overall it is hard to see any negatives.
