yes...increaing tax base nd lowering tax rates is good idea. beside this i think government should open different types of public bank account in different areas. i mean if any one intrested in one area, they can contribute in them. like defense, health, nature, farmer, poor, education etc areas.
for example i m a student. i care for defense nd poors in india. i dont feel spending money for them is waste. if government hv public bank account of these, i can gladly donate 500 rupee for defense nd 500 rupee for poor in one year. this is small amount. but if 1 crore people, who dont pay direct tax collect this money. that makes 500 crore or 60 million dollars. we can buy one tejas from this money. people should hv choice in which area they want to contribute.
