Making a profit is essential for a company to sustain. But my viewpoint is slanted towards companies that actually make products versus those that are largely "service" providers. When I see reports of service companies like insurance providers making 20% and higher profit margins, I do get an attitude about them. Like everytime I drive past Acuity Insurance and one of their building touts their "Technology Center", I feel like, "Really? Technology?" Guess I really am getting to be an old man with attitudes.
I recently retired from a very large international company that specializes in all aspects of motion control, everything from trucking, shipping, aerospace, biomechanics. Nearly all the products are high tech, requiring many materials, many suppliers, machining, handling, etc. That means the profit margins are tighter because of the costs to produce from raw materials to final product. For similar companies like Bosch, Danfoss, Eaton to make a 10% annual net profit is phenominal, and those are substantial, long term successful, sustainable companies.
