Nobody likes to be suppressed. Imagine yourself, born as a MBC. 90% of the case, your father will be having a saloon/Selling Harrack [yeah there is a caste to do that!]/Climbing Palm tree. one of this. Here your parents are not educated, nor have enough money. I agree there are many Poor Brahmins, atleast their parents are educated, which itself helps in bringing their child to a good state [ say, they buy a loan at low interest]. your father is illiterate, he drinks and is stupid. so for you, your parents are not going to do anything, the easy chance is u become like ur father and the cycle continues. but for poor Brahmins, the child has atleast a literate parent. That might help getting out of the cycle[ in most of the cases it does]. Tell me how will u break ur cycle, if the government also is not helping u pull out ?
