if you really want to know then read the islamic history by un-biased historians. they will tell you. even today the least crime state is saudi arabia, no female harassment, no money laundring, no murder, no rape, no riot, no killing, what else do you want? education is a must there for every body. it is not like shouting slogan for education and then simply sitting at home and enjoying the TV. any one who doesnt send his child for education will be jailed. that's what islam is. not only give ideas, enforce it too so that the benefit can reach to most common people too.
