While GDI itself has always run its internal economy with heavy amount of planning, a
Command and Conquer economy if you will, the pre-TW3 GDI Blue and Yellow Zone civilian side economies seems fairly capitalist from the little lore we have on them. Why does the GDI Treasury run the GDI economy in a central planned manner in the first place? Was it because the Treasury had always ran GDI's internal economy in a planned manner and they decided to run the world economy in the way they knew when that responsibility was forced on them?
There were a bunch of tiberium focused companies in the lore of course. There was Pérez-Toscano-Zelenetzky, the company won a contract from GDI to keep Tiberium from spreading or entering buildings. Supposedly working with state-of-the-art technology, there have been incidents in which PTZ made-buildings have malfunctioned unsurprisingly. From a report from W3N reporter Annabella Wu, one housing building's automatic shutter system failed to work. Kaspm's Tiberium Warehouse was an international company, that was to build safe Tiberium warehouses for the civilian population. In game, the capturable neutral tiberium spikes and tiberium silos are mentioned to be owned by private companies. These private tiberium spikes and silos were often seized by the warring factions. While GDI personnel are mentioned to usually refund the owners of the Spikes that are commandeered or destroyed with vouchers that can be exchanged for credits in Reykjavik, the Brotherhood of Nod and the Scrin did not care to hand out financial compensation to the former private owners. However, we don't see private businesses harvesting the open tiberium fields. Ithillid mentioned in an explanation (as the games don't say how) on tiberium spread to North America that presumably private tiberium farmers bought tiberium to the USA only to be turfed out by the EPA and having their feet eaten by the now out of control tiberium. Were private businesses banned from harvesting open air deposits? In the quest, all tiberium spikes so far have been placed by the GDI Treasury. Did all the private tiberium businesses collapse or were nationalized by GDI during the Third Tiberium War? I saw that some of the Free Market forum posters in one of the updates wanted GDI to bring back tiberium private businesses. There were some real life defense contractor companies still around before TW3 in the lore such as Raytheon, Mitsubishi, and Mikoyan alongside fictional defense contractors such as Otani-Lincoln Laboratories which designed the GDI war factory buildings.
Developer Mike Verdu's comments on the Blue Zones. "The place to be in 2047 is in a Blue Zone – and only 20% of the Earth's surface has been designated as such. GDI controls the Blue Zones, areas that suffer from minimal Tiberium infestation and have been relatively untouched by war. The populations of the Blue Zones live in relative comfort, going about their lives in high-tech futuristic cities that sit in forested valleys or nestle in pastoral farmland. They benefit from Tiberium as a resource; their energy-intensive economies are powered by the awesome energies generated by the green crystal – but they suffer none of the side effects that make life in the Yellow Zones a living hell. If you reside in a Blue Zone, Tiberium seems to have more upside than downside – you have almost limitless energy at your disposal and yet your surroundings are relatively pristine. Most of the world's wealth is concentrated in the Blue Zones " and "To the citizen of a Blue Zone, Tiberium provides clean power for flying cars, large homes, and a vast technological infrastructure."
Other lore material and some of the quest updates mention that the Blue Zones have a strong nostalgia for the pre-tiberium world. Lore material mentions that the New Eden reclaimed blue zone was at least partially build by private developers with a preference for designs based on an idealized version of the pre-tiberium world. The pre-tiberium world would be pre-1995. The idealized pre-tiberium golden age would be for the Western dominated Blue Zones , for better or worse, would be just after the fall of the Soviet Union and the apparent victory of capitalist free market liberal democracy. This might be a reason why Ithillid have decided that pro-free market capitalists have dedicated party in the GDI parliament while socialists are implied in the inuniverse forum posts to be merely a subfaction of the big tent Developmentalists. Incoming Yellow Zone refugees probably have a less rosy view of the pre-tiberium world. After all, what would become much of the Yellow Zones were already unpleasant places to live before tiberium arrived.
@Ithillid I am going to ask how are the GDI population receiving the heavy state control and planning of the economy?
After all, it would seem to the average Blue Zoner, that an economic system thought largely dead and discredited before the arrival of tiberium has suddenly taken control of their lives in the aftermath of the Third Tiberium War. The economic prosperity, private businesses, and large beautiful houses of the pre-TW3 Blue Zone life have been replaced by constant rationing, omnipresent state economic control, and efficient but very cramped apartments. Dr. Granger and the Treasury technocrats are mentioned to desire rebuilding the Blue Zone cities according to standardized plans with rationalized transports, communal recreational spaces, and distribution points. They also desire to empathize mass transit over the pre war GDI focus on personal vehicles over concerns of Nod converting private vehicles to military uses and because mass transit is more efficient for the compacted workforce in the Blue Zones. I wonder if some people are going to feel that Dr. Granger and the GDI Treasury are going to rebuild Paris and London into gray soulless cities in the name of efficiency and call the new apartments modern day Khrushchyovkas.
