I don't know about whats happening there, but here there are a lot of jobs that can help you make some money, not too much but you can make some money.
They refuse to work because some people have mercy and give them money.
They earn a lot of money, and they don't really do anything useful with them.
They only buy beers and drugs, the same that made them become homeless.
When I go to school I see some people begging for money in the center of the city and when I return I see the same people buying alcohol.
That happens because they loose hope and they are too lazy to do anything else than begging for money.
Yes, there are people who got there because of other reasons and they really need our help, but most of them are there because of drugs and alcohol.
