|1.||I'm all right jack|
Original saying was "I'm all right Jack, pull up the ladder".
Meaning when a man had got safely on board ship by climbing the ladder from the sea or from a lifeboat, don't bother about saving the rest of the guys because I don't really care about them.
A thoughtless self-serving person when asked to sympathise or help someone who had lost his/her job might say "Well, I'm all right Jack!".
