At present, Australia is embroiled in yet another outbreak of boat people hysteria such that 72 poor souls who took the extraordinary risk to travel across the Indian Ocean to improve their circumstances and perhaps escape political intolerance are cast as being threats to our national sovereignty. The current debate continues years of shameful hysteria which has seen our government imprison children indefinitely because their parents wanted something better. More people come in daily by air and remain illegally than will ever come by boat. Apart from my moral repugnance for the scaremongering, it appears to be hypocritical that the free market lobby always calls for the free flow of capital but rarely for the free flow of people while the left seem to adopt the opposite view. I was thinking about that today when I read that the British PM Gordon Brown has renewed his call for a Tobin Tax. How does that square with modern monetary theory (MMT)? Not very well.
