Thanks for doing something to stop the fools in wellington. I as a practicing tradesman for trhirty years are in full agreeance with you. It is about power and ignorance, fools making decisions they are not qualified to make. The same is happening throughout the government in education, non educators making rules and decisions for educators,  in health, non health proffessionals making rules and decisions for health professionals, and consistantly overiding the voices from the one doing the work, the ones who know what is best. So thanks for stoking a fire, i pass round copies of what you write and i leave them in plumbing merchants just to spread the word.
