When I was a young man I worked in a factory that produced typewriter ribbons. In our department we had about a dozen people and the man who inked all the ribbons. My job was to clean up. I was bottom of the rung. The inker was unwilling to train anyone else lest he lose his position. He was afraid and wanted to preserve his job. The big boss took me into his office and told me that the inker could not be promoted, because he would train nobody to do his job. But, the boss liked my attitude and promoted me to be the boss of the department. Naturally, the inker was angry, but he created his own dilemma. As Jesus said in John 12:20-36, unless a grain of wheat dies it has no future. Self-preservation is death.
