The second important principle which, I think, is accepted all over the world is that no taxation system should be so manipulated as to lower the standard of living of the people, and I have not the slightest doubt in my mind that the sales tax has a very intimate connection with the standard of living of the people of the province. But, with all the sympathy that I have with my friend, I again find that if his amendment was accepted it would mean that the power of the provinces to levy the sales tax would not be free and unfettered. It would be subject to a ceiling fixed by Parliament. It seems to me that if we permit the sales tax to be levied by the provinces, then the provinces must be free to adjust the rate of the sales tax to the changing situation of the province, and, therefore, a ceiling from the Centre would be a great handicap in the working of the sales tax. I have no doubt that my Friend Mr. Tyagi, if he goes into the Provincial Legislature, will carry his ideas through by telling the Provincial Governments that the sales tax has an important effect on the standard of living of the people, and therefore, they ought to be very careful as to where they fix the pitch.
