Sol economy: What is optimal for production on earth?

Follow-up-question to this scenario:
~ 2750 A.D : Quite a few asteroids/celestial bodies have been move to a stable earth orbit and are beeing mined for ressources. I am currently designing the economy (cycle).

The economic situation in orbit:

• Gold-rush style (deregulated, hypercapitalistic 'wild west')
• Freelancers and a wide range of corporations mine the asteroids.
• At the same time there is a big supporting industry for the miners. (from my research the safest way to get wealthy in the historical Gold-Rush)
• The orbit is connected to earth by a number of industrial space elevators. There are many orbital facilities and production sites.
• Much of the orbital resources are needed on earth.
• Food is synthesized via modified algae and stem cells (for meat). Basically full taste, no environmental impact and optimized nutrition and can be produced in orbit, too.
• With the availability of fusion reactors, even in micro-size (in the range of today's stove), energy is cheap.

Question: What commodity will be capable of competing when produced (or refined) on earth? Why does the orbital economy still need the earth? (economical, not for gravity and so on)
