I think there's something else psychological going on. What you describe is a rational approach based off of bad values. But I think I'm also seeing something weirdly irrational.

It's like an (emotional) depression or something. Scarcity thinking, the inability to think expansively. People are so sure that everything around them is shrinking that they feel an instinct to hunker down, shrink, and cut as well. Like it doesn't occur to them that they don't have to feel that way. The execs I work with, none of them strike me as spreadsheet-driven greedy people. They seem more freaked out than that.
