Few thoughts:- 1) Most people will not grudge a reasonable tax. 2) When tax is collected, there has to be some tangible benefit for the Tax payer. May be life insurance, Medical insurance, old age pension. A person who has paid IT for say 35o to 40 years is left to fend for himself once he retires (except the employees of PSUs, Banks and Govt). What is the Govt giving in return? 3) The IT exemption limit should be reasonable and should be linked to Retail prices of commodities. 4) A Transparent-assessment of the way the money has been used.
All these are wishful thinking. It can be said with certainty that the Govt will do such things.
