how to eradicate caste system?

According to me the best way to eradicate the system is to educate the people and this facility should even be available for the poor people, as nowadays the poor people are not having access to education as they are suffering due to poverty. If the people over the world gets educated; they will understand the rights of each and every citizen of the country. Thus, if people cooperate we can eradicate the caste system form the society. Later it will be the children's responsibility to make their parents realize their mistake and treat others equally.
