I think you are highlighting the truly important bit here - that megacorporations are economy's cancer. I am on the side that work is work, there should be no emotional connection, except for the personal relationships. It is fine that companies hire when they need resources and fire when they don't. However, a small company might lay off 10 people and they will quickly disperse in the available work pool. However, laying off 30k people at once does serious damage to the market and the prospects of those laid off people.
