On Mars, there is not going to be any low wage base people. It will cost a fortune to get there and will be expensive to live. Everyone on Mars will be high skill and high pay. There are strong financial incentives towards localising manufacturing, because importing anything will be very expensive. And yet for a long time to come scale economies will be weak. The only solutions that I can see are things like 3D printing and a lot of automation. But these are complex high end machinery that Martians will not be able to produce themselves until they number in the tens of millions. Design services will mostly be Earth based. These services are almost free to send by radio waves.

Also, how about cemetery? Deceased is buried in Mars? Cryonics? Its commercial services is charged.
Artifact replicas or originals of historical values are sent to Mars from destruction.
4) Mars orbit:
I would make use of the same satelites which we will need for radio relays and for planet wide GPS to form the back bone of a field generator.
Beaming microwave energy between them and setting up a plasma field setting by leaking argon or neon or other elements that we can control in this field to create a shield.
The artificial magnetosphere on Martian orbit is going to consume the imported energy from Venus.
Imported or local hydrogen sulfides react with mineral to generate water, sulfide minerals and silica.
Are the about one third gravity of Earth, low atmospheric pressure and thin atmosphere on Mars useful?
Can the Martian carbon dioxide be converted into carbon and oxygen in massive and economical scale? The carbon is made into carbon nanotube or other nanotechnological fantasies.

A larger perspective is taking advantage of the lower gravity and thinner atmosphere on Mars for new and exotic manufacturing by robots. Then you have carbon steel, graphene, chlorine oxides and percarbonate as bleaches, silicones, silicon-based semiconductor for CPU etc.
An important perspective on all this is that the Mars colony will be tiny to begin with so Earth can afford to lavish resources on the human population. Processes that on Earth might be considered ruinously expensive will be perfectly economical in terms of developing a Mars colony.
For example a Solar Power Satellite might be too expensive for Earth, but Martian colonists have to travel through space to get to Mars, and placing an SPS satellite adequate to all the power needs of the Mars colony, might be cheaper than hauling all those solar panels from Earth, landing them on Mars, and placing them on the surface of the planet and then having to worry about power storage at night!
If you have a small Solar Power satellite beaming a laser or a microwave beam at a receiving station on Mars, since Mars is tilted on an axis, that power will be continuously available throughout most of the Martian year.
Another case in point, no one would dream of having a portable nuclear reactor to power and heat his home on Earth, but on Mars it makes perfect sense. You could also have atomic powered cars, the problems of hazardous waste may be put off until Mars is more heavily populated and their are people who are concerned about it.

That's an interesting doc I must read in more detail. I have always been interested in use of basalt to make useful objects on Mars e.g. kitchen vessels and utensils, some farm tools etc. Using basalt dust in 3D printers could be a good way forward.

Made In Space Begins Selling “Terrestrial Offerings”
Made In Space hopes that some of their products will be purchased for reasons other than 3D printing. Advertised to museums, space collectors, and 3D printing enthusiasts, the AstroABS Canister serves as a contemporary space souvenir, identical to the space hardware currently aboard the International Space Station, and as a form of support for the Made In Space vision.
The first product offerings will focus on the plastic filament that Made In Space uses for in-space manufacturing. Four main filament products are available for pre-order today with prices that reflect their level of space readiness. These initial products are meant for a range of potential customers, from makers who want quality printer feedstock at affordable prices to zero-gravity designers who want to use Made In Space’s “AstroABS” to reduce the differences between their test prints on Earth and their planned prints in space. With the inclusion of the “AstroABS Canister” product, Made In Space hopes that some of their products will be purchased for reasons other than 3D printing. Advertised to museums, space collectors, and 3D printing enthusiasts, the AstroABS Canister serves as a contemporary space souvenir, identical to the space hardware currently aboard the International Space Station, and as a form of support for the Made In Space vision.
100% of Made In Space’s profits from all of the products will be used to further the company’s vision for creating a multi-planetary civilization. By leveraging the new capabilities that exponential technologies provide, Made In Space plans to continue revolutionizing what it means to be a modern space developer and create the necessary tools that will enable humanity to colonize space.
“This terrestrial store is a logical extension of the Made In Space explorer spirit.
