Communists are not in anyways interested in this country's development or progress.
Look wherever they have their Govt's that state has always remained backward (Kerala or Bengal) by Communists always encouraging Dharana's at a drop of a hat, Making sure people become more rebel to work (Using the word work union) and have always ensured spoiling and running of smooth and nice co's
Communists are the major losers in the current scheme of things, They cannot just wash away their hand and criticse Congress by being in the govt and then talking scrap to impress voters.
