We tried all kinds of things. Yes, we tried to get their kids to go to school. We trie to build a police outpost in their village, burned in a week :) There're NPOs working specifically with them. The only problem is lack of will on their end.
As for your upper level comment, we can either leave them as outcasts' clan or make then integrate. In their current shape, they clash with modern society too much. Stealing, begging, dealing drugs, living in unregistered shacks, squatting public parks while keeping children away from education is what put them into their position in the first place. Either we look them up for all felonies they do or they have to learn to live with the rest of us. Their "special" way of life is not something that can continue and be respected in any way.
