Pet peeve of mine: solving practical problems often involves capitalism in our system, but that doesn't mean practicality is capitalism. If you're writing ad code, you're working on capitalism only. If you're writing railway logistics code, you're doing practical work that any society needs, capitalist or not. And yes, this might involve understanding customers (or as a different system might call them, "people").

The important question would be "is this work useful," not "does this work involve capitalism."
