In this lyric, what does the "little thing" implies?

There are a couple of possibilities here! The first is that "little thing" implies luxury, but it's expressed as "little" because "luxury" isn't worth gaining if you lose loved ones - it's not very important, so it's "little." Or, it could refer to small children - it's not uncommon for people to refer to babies as "little things" when they're remarking on how cute they are. Ex: Oh, he's a cute little thing, isn't he?! Ex: Luxury is a small thing compared to having good people in your life.
