Angus Deaton a Nobel-Prize winning economist says that he would promote socialist policies due to corporatism. Corporatism requires big government and government only gets larger once it heads down the path of socialism and communism. Rent seeking relies on a captive government and can be found everywhere government touches – this includes immigration.
So rather than increasing government, President Trump’s idea of removing two regulations for every new one is a good start to ending rent seeking. Government also effectively enforces monopolies and trusts across many industries that should be targeted as well.
