The 5 year recidivism rate in America is over 75%. The justice system works by removing offenders from the general population. Not because they are making the criminals learn from their mistakes. I also am referring to talented/skilled individuals. You will not see billion dollar companies disciplining their top earners. They may discipline the janitor for messing up, but not their top earners.
Again, this is false. Happens all the time. See Nissan in the last few days. Happens in big $ business, including sports, all the time.
Perhaps we're talking about discipline in different ways and my understanding of your point of view is flawed, but your assertions here don't hold much water.
