One of the signature emotions of this particular recession, besides the populist rage that boiled over this week, is a bit of survivor’s guilt. After all, if you still have the same job or salary that you had a year ago, you’re among the lucky ones. With a different career move or two, you might have wound up among those whose household income has suffered a huge hit. You probably have friends and former colleagues in this unfortunate spot. So what can you do to help them? Plenty, it turns out.
