There was a sales manager who was raked with overseeing me and another dev finish a last minute request project. He said at one point to the other dev that he was mad at developers because we understood something that he would never understand.

This same manager would often sit in on estimation meetings and constantly say that we were estimating too high and needed to come up with faster solutions. When we would offer him with caveats of possible technical debt or unintended side-effects/performance issues, he'd want us to go with that solution. He would then complain that we were always wanting to work on technical debt and that our application was slow. He would also ask for very high level estimates for large, unscoped features/apps without any meaningful level of detail, then hold us to the high-level estimated date even after revealing additional features previously unmentioned.

We learned to never compromise on the right solution and to push back hard on dates without proper scoping. They didn't learn, so I and most of the good devs left.
