You are comparing robbery with ineptitude. They are two different things. If your ineptitude makes a 20$ loss you may not be fired as well. Billion dollars wasted at corp still is not billion dollars at the exec pockets (that would be theft and he would be facing charges). That the exec pockets millions regardles of the losses incurred by corp, even when it sounds awful to you or to me, is a problem between the corp and the exec.

Robbery and ineptitude are different things, but the situations described by OP are often special blends of the two.
