I have helped multiple friends into government housing. Housing didn't suddenly cure their addictions or absolve them of mental health problems. It doesn't remove the victim mindset. Resources such as education and work can only be done if the individual is prepared to do it. But we don't have good resources, therefore the problems are cyclical.
Trusting the word of people is not representative of what they actually do. All of these people claimed to want X but make no effort towards it. People lie, especially to themselves.
