Worth noting that Herb was actually a founder owner of Southwest, which I feel for any business is a big plus. Somewhat similar to a Gerry Harvey/Clive Palmer etc
If the business goes under then there goes all their cash and most of their pride so it is in their and your interest that the business goes ahead.
However when you get big corporations with no owner it doesn't really matter to senior management that the thing goes broke as they can just move onto their next $500k job somewhere else.
