Their lot (VP-level certainly) rotates in and out, often with 3-4 layers of middle management between them and the crews executing, which makes direct assignment of blame exceedingly difficult. Every 3-4 years you get a near-complete rotation of leadership in an area of †he business, and any memory of what anyone was trying to achieve before is forgotten, either intentionally or unintentionally, and then you do it all over again.
