timmmay:Lias: Scrap GST. Problem solved.
Scrapping GST means general tax levels need to be raised. That could disadvantage the poor if it was done fairly, or disproportionately tax the high earners. High earners already pay a lot of tax by way of higher tax rates and GST on all the things they buy.
GT is generally regarded to be a regressive tax (that is, higher earners generally pay a smaller proportion of their income out as GST compared to lower earners - mainly because they save more and have a higherproportion of their income go on non-GST things like mortage)
So scrapping GST and replacing it with a flat increase in tax of, say, 4% of income (just making up a number) would move it away from being regressive
