How might an economy in which multiple planets are involved function?

I created the above illustration to help convey my meaning, here is what everything means so that you can read it effectively:

• E = Earth
• V = Venus
• M = Mars

The dots in the lower left hand corner represent the asteroid belt. The small circles close to the circles with letters in them are meant to represent moons.

The color of each arrow notes what material the arrow represents, and the direction of the arrow indicates where the represented resource is heading.

The key for which color means what is at the very bottom of the image.

My question is: in a future setting (one far enough away that following scenario be reasonably possible), would this sort of basic flow of trade and goods make for a stable economic base for an interplanetary society that is still growing? This method is sort of inspired by the way the triangle trade worked (not the slavery part though), where one area of the world produced raw materials, which in turn were brought to another area where they were processed, to another area where they were traded for labor. I envision a similar process here, but with just people who need jobs rather than slaves. Does this system work or is something missing?
