General trends usually aren't categorically true, and this one is no different. Choice varies between people. There are people who are lonely yet can't maintain friendships with others regardless of how hard they try, and regardless of how much of a choice they think they have. There are people who want nothing more than to achieve things, sometimes things that most people would consider trivial, yet are unable to. The list goes on, which is why I don't think that blame should automatically be assigned. If someone is facing an obstacle that they'd have a decent chance of getting over, they should be pushed to try. But there's no use in blaming people who objectively have a miniscule chance of success due to things they have no control over.
