Why, is it any easier to fly angle of attack instead of airspeed?

 When will someone show that having an angle of attack indicator will
increase the level of safety of the various aircraft in service today?
Also, will the increase in level of safety (if there is any) be enough
to offset the cost of implementing such a system in all aircraft?

Both of the question are required (by law) to be answered by the FAA
prior to doing anything.
