The Professional Managerial Class (college -> management being the norm) gained a lot of steam in the '80s and had basically taken over the entire economy by the end of the '90s. My dad's career spanned the pre- and post-transition eras, with the latter coming as a very sudden shift due to a large merger. His description of the difference was... not flattering to the modern notion. Way, way more wasted time. Way more business trips that could have been an email (but how would the managers get to go party away from the family otherwise?). Lots more clueless management who don't understand WTF the business actually does or how any of it works, resulting in braindead leadership.
