Hypnosis or Merely the Power of Suggestion?

George Joseph Kreske, better known as "The Amazing Kreskin," is apparently among those highly skeptical of hypnosis. He argues that what we identify as response to post-hypnotic suggestion is effectively little more than a manifestation of the power of suggestion itself. The following video certainly presents the case to some extent: https://www.youtube.com/watch?time_continue=8&v=AqNEEG7OKFk. However, Kreskin misses the point.

It is true that the power of suggestion does in fact have great influence on how people behave. One need only look at the advertisements for commercial products and political candidates! Nevertheless, when we seek the same "suggestions" to effect behavioral modification and changes in the way we respond to external stimuli, we inevitably find that hypnosis enhances our ability to respond positively.

That said, one must concede that Kreskin, who is now 82 years old, has had a wonderful career and is quite good at what he does. I merely feel he oversteps his bounds in his efforts to discredit the art and science of hypnosis.
