Retail has been stuffed for a long time and non retail small business has been buggered for a just as long and not as a direct result of any carbon tax. We came out of a global recession relatively unscathed just recently. Labor did blow some money on crap but if there is a time to blow it then it's when interest rates are at their lowest. I work in electric motors for a small business (but on domestic and international stage) and thus carbon and mining taxes had immediate and direct impact on us yet they weren't the only reason for us losing some work.
Ridding the carbon tax won't restore confidence. Especially not while refusing to spend money to keep domestic industries and more people running out of work. People are already scared of things like the medicare co payments, debt levy (or, 'tax tax') and the rest of the junk Wingnut is trying to hamfist through. You can label the carbon tax anything you like but it was still revenue. Increasing the GST is the obvious goal.
There won't be anything like an ETS or any climate change action in place as long as the catholic cabinet is in place as they don't believe in it. Trying to spend federal money on putting catholic counselors in schools, to trying to divert funding from the royal commission into church sex abuse into Labor's crap insulation scheme, to trying to remove the tax exemption of non christian charities, removing the minister for science, he has played his hand. No interest in progress, just making sure god's work is done and his mates can keep selling Foxtel. There is nothing for Australia from these pricks at all.
