When a helper fails to advocate for these people, it's wrong to conclude that they didn't want the help - a moral judgement. The help being offerred might not have been good enough, or the person might not have been ready for help.
In the end, whenever we do get to help someone we should be happy (since that improves the work. But when we fail someone - or we think someone has failed themselves - we should not be bitter, but become better at finding those who we can help, and improving what we offer to those we help.
I don't think you would doubt any of what I said. Instead, I think you're here to defend a morally negative view of students and others who "do not want to work" for the help. And I think that's wrong.
