The candidates for the Labour leadership are in an awkward position. They are campaigning for the votes of party and union members while aware that anything they say may be taken down and used in evidence against them. Commitments they make to a partisan electorate may be difficult to reconcile with a wider audience.
The election has become something of an auction with one candidate or another making an offer and the others seldom ruling it out. Whoever becomes Labour's leader, the party will not be obliged to go to the general election next year with a Pasifika TV station in its manifesto as well as the usual promises to repeal National's employment laws.
But the most interesting suggestion so far comes from Grant Robertson, endorsed by David Cunliffe, to raise the minimum pay for employees of the state and its contractors to $18.40 an hour. This is the "living wage" promoted by the union movement.
The living wage calculation is a useful guide to the labour market. As an authoritative measure of the minimum required for a reasonable living standard, it ought to be noted by small employers who take their cue from the statutory minimum, currently just $13.75 an hour. All the candidates would increase that rate, too. But it is one thing to promote a figure for wage bargaining, another to impose it by law. Unemployment would rise if industries could not absorb the extra cost.
Everyone agrees that New Zealand needs to lift its incomes overall, to match Australian rates if possible. But the Labour Party seems to think that this can be done at the stroke of its pen. Mr Robertson in particular, is talking as though an economy is simply a job-creation scheme and all that a government needs to do is make its priority "people".
