Indian communists have always performed the function of show stoppers everywhere. They support something today, and oppose the same thing tomorrow, if the situation does not suit their whims. They are noise-makers par excellence.
They don't know what their aim or agenda is or where their priorities lie. They are drugged by their faithfulness of an outdated economic theory.
I hail from Kerala, where the communists are having a see-saw power sharing with the congress. Years and years of communist rule have only served to tarnish the name of the state. The state's industrial environment has taken a beating. There have been innumerable instances when the trade unionists would interfere with production units that run well, organise strikes leading to eventual shut-downs of the units. Victorious, they leave the place. The labourers who depended on the factory for their daily bred are left with to deal with harsh realities of poverty. The famed economic theory has NO solution to fill their stomachs!
The communists who are a bunch of hypocrats would be doing a great service if they just quit public life and keep quiet somewhere.
