I agree @MrsFinkelstein
Moaning because he does something to highlight an issue. Would also moan if he did nothing.
Homelessness doesn’t come itself. It isn’t just about money. I’ve been so close to it and it terrified me.
Ex-forces can end up on the street having failed to adjust to civilian life/trauma from things they’ve seen or done. Discord with a family member. Death of a loved one. Feeling a need to escape after being judged/ belittled/criticised. Not being accepted as a valid member of society. Family scandals. A need to escape from the life you have. Pressures borne of the expectation of others. Many more examples I’m sure.
It isn’t just about a lack of money (although of course it can be a factor).
Despite the money some have (or not) - the luxury lifestyle someone may have - (or not), there are issues that affect you. Not many in life can say they have a perfect life or problem free existence.
Ypu may look at a person on the street and think a prince would never know of the troubles they experienced.
But it could be argued - financial burdens aside - that they know those troubles all too well.
