My opinion, this topic goes back to the FAA not requiring Stall and Spins.
Over the years the students have not been "comfortable" with unusual attitudes so, they don't have any basic maneuvering skills. If a pilot is uncomfortable with aggressive flying than one day they decide to go play a little because the weather is nice...
You can't feel the aircraft if you're all white knuckled on the controls. Sensing a stall also takes awareness of the aircraft's lift and attitude. Students should be trained on how to practice unusual attitudes at higher altitudes where mistakes in recovery are safer.
I was given instruction early on how to practice slow flight maneuvering. The instructor had me go through a series of stalls (power-on, power-off, in a bank and excessive pitch changes) every week. He didn't want me to be a moose stall statistic. Many of the high time pilots that mess up and hit the ground haven't practiced in quite a while before their accident. Just like any skill, if you don't keep in constant practice you loose it.
