The more successful the m&d, the less likely he is to be radicalized, especially for business owners. They tend to be more pragmatic and follow the bare minimum of their religion. The more islamic ones are usually those who are poor, and they believe that if they are more intolerant and radical, that might perhaps improve their lot on earth or give them better chances of going to heaven.
PAS in Kelantan and Terengganu, militancy in Aceh and Marawi are good examples. Poverty and highly islamic societies go hand-in-hand.
