Increasing the cycle of poverty

How will scrapping selective education reduce the "cycle of poverty" in Northern Ireland? Social mobility in Britain has declined since Grammar schools were scrapped, why should Northern Ireland be any different?

"The facts on social mobility are depressing. As the middle classes expanded after the war, there was considerable movement. But since the early 60s academic surveys tell us that mobility has declined. Studies show that for people in their 30s, the social class of their parents matters more than it did in the past." - Ruth Kelly, Education Secretary.
