We've all heard the old joke about how five Irish people on a desert island would form three political parties, but we never hear what happened next. The two on the left voice their opinion that collective pooling of resources and intelligence would swiftly guarantee a scheme for escape. The lone liberal demurs, arguing that each individual should devise their own plan, with personal ingenuity and enterprise determining the most effective outcome. Meanwhile, the two conservatives ruefully shake their heads at the mere idea of such a foolhardy, life-threatening endeavour, declaring the best option to be the formation of a new desert island civilisation. Ultimately, of course, all five swiftly die, having only agreed to postpone further meaningful debate.
