The last one I think that is a nation state as rational unitary. That mean the state is part of the centralized economy. The industries that are necessary to build and sustain the national strength. Only state can do this such as the train MRT and aviation business is a state contracts. The government can intervention and control the price of the ticket, not the inflated stock. People can be consumed without affecting the public revenue. I think the Government had maintained control of public bus service charge rate is particularly justified. Because if there is a high service charge it may be a directly affects to the life of citizen.
