Fair. The greater point was that you're not just "helping the business" by maintaining a clean environment (whether the "dirt" be carts or excrement). You're also helping your fellow humans.
And, in fact, you almost certainly are helping employees. Sure, there could be fewer of them, but they'd be doing less menial work. And the ones who got laid off due to your contentiousness would find less menial work elsewhere. Society as a whole would benefit.
You probably already know this, but the idea that we should make the world worse to preserve people's jobs is called the broken-windows fallacy.
I probably should have just responded with that originally.
