The problem is; wait another year and it’ll be, “get fired from their fifth job.” Alas; getting to that point, enough times, is what it takes. Once there is no time left, and no money left, and no food left, and the littles are too listless even to cry.
Get to that point a few times (eg: 1789, 1848, 1968), and you start choosing to stand in the tear gas early.

You can inflect them to imply all three things go in, but I prefer pausing after each comma, suggesting that the third item in the list includes “in the ass” as part of its identifier.
