I think it is interesting to read,with all these arguments against changing the rules, such as the carbon tax, becuase they will make our industry uncompetitve comapered to others that the same arguments were put forward by those who wanted to stop the laws preventing slavery over 100 years ago. They argued that a nation without slaves would not be able to compete with one that did have slaves. But still they (the brits) took the gutsy step of banning slavery.
