I think the description of The Big Issue from their own web site best describes what these people are doing and selling. I am not sure if there are similar magazines and programs for those in hardship in other countries but this is very commendable approach to help people help themselves.
“The Big Issue is a fortnightly current affairs and entertainment magazine that is sold on the streets of towns and cities throughout Australia by people experiencing homelessness or long-term unemployment. Vendors keep half of the cover price ($4) of every magazine they sell. It is the magazine that helps people help themselves. It is also Australia’s fastest growing magazine with readership now at 157,000 readers.” The Big Issue Australia
