Muslims do love the worldly life, but they love it for all the wrong reasons. Had they loved it for progress, creativity, innovation, & civilization; they would have certainly succeeded. I feel things are changing now, people desire to do more than just live & entertain themselves. More & more Muslim majority nations desire to have an impact on the world. Things are changing, but the change is a bit slower than desired at the moment. People need a good environment for them to flourish, think of a noisy classroom; it's hard to study in such an environment. A person is able to concentrate & work harder in an environment where there is peace & order, combined with a good mentor of course, in this case; that role would be played by the leader. So once Muslim societies begin to correct themselves, they are bound to improve. The first task that requires us to acknowledge or find & accept a majority of our problems has already been undertaken, now all that's left is to solve them permanently & move forwards.
