why not tax the resources?, page-19

Ok for ten thousand output costs you make ten thousand profit and pay 30% tax .Now because prices go up because of market demand futures etc etc you now make twenty thousand for the same output cost of ten thousand you pay 40% .If because of market demand futures etc etc your output cost remains ten thousand but your profit goes to five thousand you pay less than the 30% tax. Its how i see the proposed tax works with out going into the complex parts of taxation.Is it that how you see it ? As for the builders we know they are ripping the goverment off that happens to alot of goverment subsidised projects.Its a shame but how it is.But yes if they double the price of the buildings for same amount of cost it would be scary.But the the same never the less.
