No statistics to share, but I recall one man who was very prominent in management: Al Perlman.
He made his mark in tackling BIG problems. In his career, he worked at Rio Grande, New York Central, Penn Central (poor fellow!), and Western Pacific. At the first two he is almost a legend for his success either in helping the company recover from bankruptcy or in forestalling it. At PC, he was caught in a hurricane of troubles. At WP, he and some loyal proteges shaped up the company after it had dropped the California Zephyr and had avoided bankruptcy also.
He's generally remembered as a very strong and proactive business leader trying to shake up a then-hidebound industry. Probably his worst career move was in NOT resigning as soon as the misbegotten Penn Central merger took place. The mess wasn't his fault, but everyone in authority got splattered with mud.
