The reasons for emigrating

The other day some Senegalese people came to our "Writing Techniques" class. We wanted to understand the reasons for them to emigrate and its consequences. They were four boys, but only one of them could speak Spanish. He told us that most of them wanted to come to Europe to earn more money than they did in their own country, but they didn’t intend to stay here, in Spain, for a long time.
The ones who have papers come here by plane, but the rest, a lot, by "caiucos". In their countries, the mafias which organize all these trips tell them that they won’t have any problem, that it is really safe, and that when they arrive here they will have a job and (they will) live better.
But reality isn't like this. First the foreign language is a problem, then they don't have a place where to live if they don't know anybody here, besides it isn't easy to find a job...
So, a lot of them say that if they knew what awaited them here, they wouldn't come; because at least in their country they have people who can help them.
Fortunately, there are some associations to help them and these associations are a big support.
See you soon, write me posts!
