Keith, if we are talking of world unemployment, there are both left-wing and right-wing governments in countries where unemployment poses a problem.
Greece's Socialist Pasok party passed in a few years from about 50% of the vote to 13% in 2012, and now struggles with only 6.5% popular support (among those who'd still vote).
As for Britain's Labour, 13 years in government made them the most incompetent government in British history.
The solution to unemployment does not depend on whether a government is left-wing, but whether there is the will to help people find work for an acceptable salary.
It's essential that Local Government be given the powers to help the local people in their administrative area to FIND WORK.
Nothing really to do with politics at all.
But a Local Government must put the interests of its own people first, for whom it has been elected.
