Firing middle managers is a fun way to kill the company. Not that cleaning house is a bad idea. Unfortunately the people making decisions of who to keep and who to let go are usually idiots.
Middle Managers are promoted for two reasons: technical expertise and ass-kissing expertise. Now the technical experts tend to not mix well with incompetent parasitic c-suite types idiots. The ass-kissers are beloved by the c-suite as that is their only role in life.
So when firings come around guess who they get rid of? Then 1-3 years later everyone is shocked when everything starts to fall apart.
