> Tomorrow if your salary is cut by 50%, would you cut-down on extra expenses? Is that a sign of mismanagement from you?

if you knowingly and willfully put yourself into a situation which resulted in your salary being cut by 50% then yes

It's still worth it to a apply for a job that pays double or take a job that pays double. It is only a personal failing if you misunderstand the risk and cost going in.

I'm not sure if you replied to the right comment or not since I didn't say anything about firing engineers (or anyone).

My point is that over-hiring and layoffs aren't "good for the company" as the post I was responding to claimed. They're both a sign of bad management that incurs a cost on the company being poorly managed. One of those costs is that top performers leave as they are the first to recognize mismanagement.
