I'm not specifically saying layoffs are good or bad, I was giving an example of how something being common (layoffs) doesn't automatically make it good (it's of course not good for the fired people).
Of course, certainly not for many of the fired people (although depending on severance and situations--once I would have been happy to have been laid off). And layoff, and the way they're conducted, can certainly be conducted poorly and with less empathy than is called for. (Though, in reality empathy mostly=money in this context.)
