Why should only Shudhras work for the other three, aren't there any shudhras with brains and aren't there any Brahmins with no brains and should they still guide the society with no brains. The dharma itself is lame. You, by supporting it are racist and castist.
Any body who can put their body and mind to work should be allowed to do anything they want and not based on caste. And that's what the root of problem in India and you are just supporting that. I belong to a forward caste but just hate the bloody Caste System in India. Unfortunately, Indians living in USA too are very much into it. "You can take a person out of the country and NOT the country out of the person"
