In India, some citizens indulge in irresponsible activities like public smoking, spitting and getting drunk to disturb the public. One other issue in India is caste system that links one's birth to his rights to get a job / educational offer and has nothing to do with one's financial status.
People who are poor and well behaved might loose opportunities if they are designated forward caste. To promote the ethical behaviour of a citizen, it might be interesting to link caste system with his societal ethical contribution. People indulging in public smoking if caught could be designated in forward caste for few years to make them loose their opportunities and cause a potential fear in them not to repeat it. People who are well behaved could be designated backward caste to make them benefit and contribute.
Such a dynamic system in caste would be useful to help people from misery related to poor job opportunities just because their birth puts them in a particular caste system. Such system might help in reducing poverty as well.
