Can't say I'm an expert but I have taken surplus food from events that I was involved with to the local shelter....
Talked to the fella there who ran things, he maintained that most of the people who stay there have jobs but just can't afford to rent or buy anything.....
Now these people may not be immensely qualified but they are out there trying to pay their way and failing because the jobs they can get don't pay enough.....
Just a bit of anecdotal "evidence" from the frozen north, and no Rrhain I never published it anywhere.....
