Please elaborate. As it is, this flew over my head.
I'm guessing it's a reference to how rich people can end up in more pleasant, less restrictive conditions. This is nominally based on security level, but plenty of people seem to think that social class has something to do with it. See, e.g. the notion of Club Fed [1] and how things go for people like Brock Turner [2]. Or Ethan Couch [3], the "affluenza" [4] kid.
It's to do with British English vs. American English. In the USA, a TV remote control has batteries; in the UK, a telly clicker contains batteries.
My remotes have batteries. The box I bought the batteries in contained them. Now they’re in use, they’re not contained as that’s a temporary state before use.
