There's a lot more going on here than just the initial question "is shoplifting morally 'fine'?" But I'd like to throw the obvious answer out there that not only is shoplifting from big box stores not "morally wrong," it's morally virtuous. Expropriate that shit. This is true regardless, but especially if the ghouls who own those stores are going to falsely blame shoplifters for the evil shit that they themselves are doing anyway.
