well, that’s true that in many countries that has majority muslim population the social development is pretty bad. but i think islam isn’t the reason for that. speaking from my own experience, i’m from uzbekistan which has more than 80% muslim population. but the reason for the economic and social challanges is that they don’t practice islam. everything is by bribery, selfishness and all the things that’s prohibited by islam pretty much exists there. when i think about it, islam would be very good solution in my country. In US and England, the system is more islamic than those so called “Muslim” countries, For example bribery does not exist, good opportunity to get knowledge, human rights, and as general more open minded people. that makes them developed countries in my opinion.
