As a supporter to Capitalism I prefer the tax system bin gulf countries. There is no income tax. Only corporates have a tax that too in a small percentage as low as 5 percent or so. But liquors and cigarettes do attract a tax with higher rate.
From today onwards India has a new tax system called GST ( goods and services tax ). It is a good system to collect more revenue to government. But I can't see anything good to common people as tax rates are high in India when compared to middle east.
