Alright, then what what does income from trade represent? What does income from towns represent? I stand by my original point. The corporations in BTS are state sponsored and are not representative of private sector businesses.
The simplest proof is that some of the BtS corporations generate culture. When did state-owned companies ever do that? (Other than Monty Python...)
Seriously, towns and trade represent the smaller-scale economies that existed hundreds/thousands of years ago. Correspondingly, there's a relatively big boost for early luxuries - gold, gems, spices, silk, etc.
Now, take the techs required for Civ corporations
From the period 1850-1900:
Combustion: First oil wells drilled, kerosene replaces whale oil (Combustion obsoletes whale in Civ - whaddaya know?)
Refrigeration: Commercial refrigeration (shipping, railcars)
Railroad: Obvious, but US transcontinental RR among others ~1830-1900.
Medicine: this is an ongoing tech of course, but this was the time of Lister (antiseptic surgery) & Pasteur (vaccines, germ theory), etc. I am sure others here know more than I do about this, but that time period must have been a quantum leap fwd for medicine.
Plastics: commericalization later, but this is the Ethanol company, and ethanol was used in the US in the late 1800's (before oil wound up being cheaper, ironically)
Rocketry: Tsiolkovsky's (the Civ quote guy) most important work dates from 1903. Not the best fit, but it is a space race tech...
Mass Media: OK, this one is later. Radio would be a better fit imo.
BUT! Just as with religions, for game play purposes you don't want everything available at the same time...
In the second half of the 19th century, the US had a number of
private sector mega-corporations (to use a more modern term!) which achieved near-monopoly control over markets; I mentioned some of them in an earlier post. This seems to match up rather well with the requisite technologies. It is too good a fit to be anything else.
The Big 7 corporations in Civ are public sector corporations.
If the corps are state-owned, then riddle me this:
Why are they cancelled out by running State Property?
