If you're playing Terraforming Mars you want to build your "engine", in terms of resources or points generated per turn. The usual way to achieve this efficiently is to use up as much of your current resources as possible, so that they can compound over the course of the game. An innovative company should thus have costs exceeding revenue, as the costs should lead to future profits. It's of course possible to have costs that do not end up generating any kind of profit, but it would be a bit strange to see a company that has valuable ways to deploy capital simply refuse to do so
