Hari Roka is not worth countering. Were it  not been his position as a MP (unelected, and of a parliament that had mandate of two years, but let's forget that), which allows him to spoil good things in the system, I wouldn't have written even a paragraph on him.

Let's not argue based on some film or documentary. 

Now, please tell me what "mixed economy" is. Without defining it properly, we can't debate it. In every textbook of economics of modern era, there are instances where government has a role, even monopoly firms have a role. For example, firms that have economy of scale or firms that provide 'public goods' are better off as a monopoly or being run by govt.

In our country, unfortunately, government is a failure at these very fronts. Electricity industry does have economy of scale, but what is the situation? Do I trust these same jerks to run my banks? Don't we know how govt used to run the banks? All the politicians used to get loans and get waived, even in Panchayat era. Hell, we had to invite KPMG to go over our national banks. 

I don't believe private sector will be squeaky clean, but our efforts should be spent on running them transparently. Unfortunately, Roka and his ilk wants to set salary of a private bank, among other things. Go figure.

[Basically what this jerk want to do is: in OUR money, in OUR bank, this man wants to set the salary of OUR employee. He doesn't have to invest, he doesn't have to bear any other consequences. As for discredited system, this jerk works right under the FLAG of communism which has not worked anywhere in the world. On the backdrop of such a colossal failure,  this man talks about failure of capitalist economy.]
