While he may have brought order to the Land of Oz, and perhaps his reputation kept the wicked witches at bay, he was a fraud, in far over his head, and eventually was discovered.
I often wonder if this simple man from Omaha was in a position similar to that of the so-called modern day prophets. I doubt he had a malicious and power-hungry motive in taking the seat of power that was set in front of him. More likely, he did what everyone expected of him, and fit the role that he felt was needed. Similarly, I find it noteworthy to read some of the things past presidents and apostles of the church have stated regarding their personal experiences which separate them from other members (click here).
It seems to me that the leaders of the Church today are not that different from the little man from Omaha, putting on the show that the followers expect, pushing buttons and turning dials that keep up the deception that they have superhuman abilities. Whether the man is hiding behind a curtain, or claiming to see beyond the "veil", the principle is very much the same. And just like the trusting people of Oz, believing members of the LDS church trust that Thomas Monson is exactly what he is built up to be, paying no attention to the mysterious curtain (i.e., problematic history) that would expose him as a mere man.
