My employer, who pays me to write software. As we can see, writing software without seeing to it that the road gets built makes me X dollars, but writing software while seeing to it that the road gets built makes me X - Y dollars, where Y is the cost of seeing to it that the road gets built.

If the idea of me being obligated to spend my personal income on this matter makes you quibble about the definition of income and profit, pretend I'm a contractor with an LLC, and my LLC pays for the road. Either way, that's immaterial. I am letting people die by not building that road.
