In Australia we have a 'high' minimum wage, the tyranny of distance affecting freight costs and a small population which limits how much stock can be sold locally. These increase the cost of doing business more than the (dodge-able) corporate tax rate.
However, we have universal education, many world class universities & we punch above our weight in research. We have universal healthcare, reasonable road and rail infrastructure and stable government. These all increase productivity. We also have a low dollar, speak English and are on Asia's doorstep.
All of these factors make Australia a very attractive place to invest. In my view, a race to the bottom on business tax is a surefire way to reduce that attractiveness.
