Hans is right, this is not a logical exercise to make a real world result. What we have here, besides a failure to communicate, is a game mechanic result. One you would recognize as the result of a random set of output from a 2d6 roll.
Of course it's the result of a game mechanic. EVERYTHING is a result of a game mechanic. If you want to fly the "game mechanic" banner, we may as well reduce our discussions to typo's in the rules.
It would appear to me, and you seem to missing the point entirely, is that individual worlds are equivalent to countries here on earth, regardless of size of population and how much a planet wit 20 billion pop outweighs the entire planet Earth.
You're doing that whole "mechanic" thing again, right? "They're not really planets, they're countries that look like planets, and randomly generated countries at that."
But discarding the mechanic thing, that's not true, is it? Countries are resource constrained due to national and natural borders. Planets, ostensibly, are not. Country Japan has little oil and natural gas, relying almost entirely on imports. Planet Japan, ideally, would not have that problem. (The discussion about the distribution and concentration of natural resources across planetary systems can be on some other thread -- for all we know, Earth is unique in the richness of it's carbon based energy sources, or gold, or uranium, or whatever. For all we know, all of the other planets are just made of Dirt™. But for now we can project that Earth-like planets are, well, Earth-like. Oh, wait, we have ubiquitous Fusion power -- who gives a flying leap about carbon based power. "What's fusion power?" -- Random Louzy Citizen)
Bangladesh has a huge population. Is the TL of Bangladesh higher, lower or equal to the U.S.? While there are high tech pockets, on average they are lower.
What is the reason they are still behind the U.S. in TL if it is so obvious that they could just import the manufacturing capacity to make it themselves?
Another comparison: Is Germany higher or lower TL than Greece? Why?
Is Japan higher or lower TL than China? Why?
Another has addressed much of this. You'll notice that most of the delays in technological and societal progress has been due to internal political strife. But even then, this is over a short period of time.
China is in the midst of it's industrial revolution as we speak. The West had it's IR mostly during the steam age. China is having it during the atomic and information age and part of the process is moving from an agrarian economy to an industrial one combined with the urbanization of the population. There's a reason China built the equivalent of 2 power plants per WEEK in contrast to how few the US is building. And that only slowed down 5 years ago!
The GDP of the developing countries are rocketing practically straight up. Look at most any graph and you see them make practically right angle turns.
So the issue is not that these places exist. The question is how do they continue to exist, in the midst of high technology societies. How do they persist and maintain their existence over hundreds of years, generations of people, not 10 or 20 years. How do they sustain their "primitive" ways while resisting the influences.
And that's all fine and good for more lower tech societies, smaller populations, or those with (what I would consider) oppressive governments, that are either very isolationist or suppressive or both. Information, as we are learning, can be extremely subversive.
But, Regina? TL-12? A sub sector capital? Seriously?
"We're TL-12 and we like it." -- T-Shirt in a Starport gift shop. Matching hat available.
"Jump 3 should be enough for anybody" -- Duke Gates.
"TL-12 Engineering was good enough for my great-great-great-great-great-grandfather, it's good enough for me!" -- Freshman Engineering Student at Regina Tech, Class of 1115.
"How come I have to buy this new Engineering book for Cr 200 when it's got the same stuff as my great-great-great-great-great-grandfather's?" -- Same student in the campus bookstore.
"Oh, we're going to Regina, better bring the power adapters, they still haven't caught up." "Well It's only been a few hundred years. Some day they'll catch on." -- Overheard discussion between two unidentified Imperial staff.
That's utter nonsense.
Maybe once you hit Jump 1, it just doesn't matter. TL 10, 11, 15…now you're just splitting hairs. Fine, I'd buy that and simply make Regina TL-15 by fiat. "You are now TL-15, go forth and import some technicians, tools, and textbooks."
So, yea, a random mechanic created this galactic pin point in the universe. But the background story doesn't fit. What are the Imperial Historians hiding from us? How does a 1000 year old society, with access to untold wonders, that advances said wonders, let these backwaters remain? And if you want "Cuz the Emperor says so", fine. What about the Zhodani, Aslan, or Vargr? (Well, maybe not the Vargr) They seem to be more slanted toward the success of the larger social order than the Imperial Laissez-faire "as long as I get my taxes, what do I care" system.
But in the Imperium, why aren't the Nobles clamoring for it? "What's the point of being rich if I can't spend my money anywhere because of exchange rates!" More trade, more taxes, more shiny things.
None of it makes sense.
Yea, yea, I know. "random mechanic" It's all meaningless.
