It would do no harm - and possibly a great deal of good - for New Zealand to know the minimum a person needs to be paid in this country to have a "living wage". A living wage, as the union movement is now proposing it, would not be a statutory minimum. It would be an accepted figure with moral force, no more.
The round figure, based on a calculation by the Anglican Church's Family Centre in Lower Hutt, could be $19 an hour, considerably more than the legal minimum adult rate of $13.50 at present. The Family Centre has added up the costs of a basic diet, the rent of a three-bedroom house in a lower quartile of value and some other expenses of two-child families in Statistics NZ's household surveys.
There will be plenty of scope to quibble in the detail of those costs and about whether all of them are absolute necessities. But there is no argument that life on the minimum wage must be a struggle. If a nation could simply legislate a comfortable living income for all its citizens, every democratic nation would do so. If only economics were that simple.
If the living wage proposal was to have legislative force, raising the statutory minimum hourly rate by $5.50 at a stroke, there would be increases in both unemployment and inflation as some employers reduced staff and others increased their prices to recover their added cost. Either way, the economy would suffer and nobody would be much better off.
