Why muslims are like this??

I always wonder muslim community make fun of India by saying "4 Trillion Dollar Economy" "vishwaguru" but on the other muslims community have least contribution in India's GDP and have the lowest literacy rate in india doesn't have the civic sense either they don't even pay taxes because they don't earn much also not any run big companies except Azim Premj. Why their community always criticise india if they have zero contribution for their own country
