Of course they are right, for IMFs' sustainibility, and poor people inclusion.
One of the more important Burkina Faso IMFs is doing so.
BUT:You have to look at the regulation rules implemented in the context: If no, you can see an IMF collecting money from poor people just to lend it to the private owner of the institution, as I saw in Cameroun.
And a good balance is not so easy to find: In Romania, most IMFs have to focus their market on small sized enterprises rather than on poor people' ones, because of the regulation constraints.
SO, let's have a very accurate study of this very important question, as we try to do in our Chair.
