Politicians just do not get it. They have convinced themselves that they can tax whatever they desire and people have no choice but to pay. Missing in their analysis are two influences (1) people just stop earning income for it reaches a point it is not worth working anymore, and (2) you simply pick-up and leave. Modi and his assault on the Indian economy has created a massive exodus of the upper class. India is also witnessing a massive migration of its rich headed mostly to the USA. They are number two on this net migration outward whereas China is the number one place the rich have been leaving. The latest statistics show that some 7,000 high net worth individuals left India which was a 16% increase over 2016 figures. France also saw net migrations outward when they went crazy raising taxes.
The same part of this trend has been a serious violation of human rights. If everyone is supposed to be equal, then why is it if you earn more than the average it is perfectly fine to hunt you down and discriminate against you because of your intelligence. If it is wrong to discriminate against someone who is mentally incapable of a normal life, then it should be equally wrong to prosecute people who are above average.
