A life loser.
Nothing but bad decisions and actions and then blame everyone.
It appears to me that gnomish Dave
thinks he needs a certain minimum of things in order to get by.
The idea of doing without, doing with a substitute of some sort, or changing one's life-style so as to not need that thing, whatever it is, any more, doesn't occur to him at all--even though you and I have been acquainted with the concept since we were knee-high to a grasshopper.
If the guy gets that social security disability where one never paid in--I forget which of the two it is--no matter how much it is, it's not going to be enough.
Such is the fate of people who think they have no obligation to at least
try to get along without something.
