What exactly India's left want ?

So here we have the news that Indian communist parties are planning to celebrate the visit of Venezuelan president to New Delhi. Its amazing to see how India's left has consistently stabbed Indians in the back. Look at their track record, Calcutta is in dump. Only after seeing the success of Bangalore in Software technology, they have finally invited Wipro to open a software development center in Calcutta. In short, most of the time of these Indian left parties is spent in hating US and spreading anti American/anti capitalist propaganda among the public. They have nothing to show in terms of their track record in showing economic growth or infrastructure development. They would be very happy in seeing a poor unindustrialized India so that they can continue to spread their ignorant stupid propaganda about "greedy" capitalists to masses.
