Why is it easier to pull than to push?
Whether it's easier to pull than to push depends on the circumstances, there is no universal principle here. If you're using the pulley suspended above you can add your weight to your arms force and thus amplify your effort(pushing a rope doesn't produce any result of course). If you were to move a heavy stone block it might be easier to push it, if there's no grip possible to pull.

How does a movable pulley make work easier?
A fixed pulley is the only pulley that when used individually, uses more effort than the load to lift the load from the ground. The fixed pulley when attached to an unmovable object e.g. a ceiling or wall, acts as a first class lever with the fulcrum being located at the axis but with a minor change, the bar becomes a rope. The advantage of the fixed pulley is that you do not have to pull or push the pulley up and down. The disadvantage is that you have to apply more effort than the load
