It could be that finding oneself at fault for life choices but being without enough motivating energy to make better choices is an even worse personal outcome than blaming others, and deciding to externalize blame is a defense mechanism against crippling stress/shame that such people have developed consciously or not. It may be far from helpful but it prevents people from feeling trapped if they give themselves something to crusade against.

I think people that are quick to blame external factors would be more visible towards others than people who do choose to blame themselves, but even in the case where the latter feel trapped with learned helplessness and unable to act. There isn't much to say to the latter except "it's hard, but you should do the work." Which I would believe they've heard thousands of times already, so it only makes them feel worse. Such dialogue by its nature doesn't make for "engaging content," so to speak. Whereas a lot of (bullshit or not) arguments arise with the former that serve as a more effective distraction.
