Ouch with those down votes. Prolly don't say "all" cause absolutes are almost always wrong. But the sentiment is correct. They're not in those positions because they're technically smart, but because they're good at social climbing and empire building. And in my experience exceptionally bereft of integrity. Layoffs are a tool in their C level signaling system. Maybe they're good for the company and maybe they're not, but they're doing what the other C levels are going so they're mostly safe from repercussions and scrutiny.
