I've been on that side myself whn i was about 20, so i can speak from experience, i have done something about i and i've got out of it and have a good job, own house, nice car and a wonderful family, that's not to say it's easy, i just got lucky i suppose, i got myself a housing association house in a rough area of Manchester and from having a base address got my life together. When i was homeless though, i would never beg, i didn't think it was moral, but i don't disagree with it, i wouldn't give a beggar money though, i'd happily go and buy them some food / a hot drink though, and have done before. The big issue is readily available for them to sell
