I'd say it's actually opposite. Same day pay means that they can't fire you unless they have the money in hand. Someone who can wait a week and a half before paying you their final paycheck can fire you whenever they need to. Same day pay means they got to have that paycheck first.
As for Rich versus poor imagery? That's so transmutable as to not be worth talking about. Completely ephemeral. Heck you eating lobsters used to be a sign of poor class, now it's the opposite. Things like perception can change very quick. Besides seeing is so much CEO pay is tied up in stock options these days I would argue that they are paid immediately even more than anyone else.
