Consider an industrial farm that only produces almonds at enormous expense to the regional ecology and grossly depletes the topsoil and water table, versus a family-owned yacht builder who builds from sustainable sources.

Nom nom on those roasted almonds and slurp that almond milk, but keep in mind that yacht builder is having less of a negative impact on the planet.

That's a good point, and what I was angling for - we should be allowed to take the ethics of a job into consideration. That the existence of yachts means someone has a job making yachts doesn't automatically make yachts, or their creation, ethical.
