This seems like a strange thing to post on Hubski. It might be good for India's rich and middle class, increase the capital pool a bit. Doesn't really mean much for India overall. The real problems in India economics are barriers to foreign direct investment, a maze of bureaucratic and regulatory obstacles, corruption, the need for MASSIVE increases in infrastructure spending, and the Maoist insurgency.
Maybe you just hope to show the different capital gains regimes in our two countries, letting us know how good they have it in India. I personally don't favor making our tax structure's less progressive, which is what a large cut in capital gains does. Making productive workers pay more taxes compared to people who make their money sitting on their asses watching the ticker tape doesn't seem right to me.
Cutting business taxes in half (or more), eliminating most deductions for business and increasing the tax rate on the highest earners would be a good thing for the U.S. to do, but unfortunately is probably a little to complex for our current political situation. Lack of access to capital for big business doesn't seem to have been a problem in the U.S. for a few decades, if anything our bubble prone economy seems to indicate that it might have been the cause of some of our problems.
