Unless I own stock in the company, the severance package of the CEO doesn't concern me any more than the hourly wage of the burger flipper. If I have partial ownership of either company, i.e., if I own stock, then I have a say.
If I have no stock in the company, and therefore no stake in the deal, preoccupation with the terms of someone else's severance package smacks of nothing more than plain old-fashioned jealousy.
I'm not preoccupied -- I'm amused. It makes me laugh to watch the TANSTAAFL, "everybody should be paid what they deserve" free market True Believers try to defend these slimeball con artists as they eat one Free Lunch after another at shareholder and employee expense.
As for jealousy: I have my own business and couldn't care less what anybody else makes. My family and I live in the magic land of Enough and are happy to do so.
If the few get too much and many get too little it is dangerous. Too much wealth or power corrupts while poverty demoralizes. Jealousy is a natural instinct like thirst or fear or feeling of pain or sexual desire, it serves a purpose.
Without instincts the mankind would die out.
