I shouldn't have insinuated the entire harem trope is bad, but I don't think I can argue against most of the stories being bad. The only one that comes to mind that did fine with it is Mushoku Tensei, the LN at least as I'm holding out on the anime for a few more arcs/volumes.Way off topic, I'll check out this story at least. I feel like it's hard to get the whole system trope to work these days without it coming off as stale or shallow, so I'm interested to see how it's done here.

Maybe, my only issue with harems is the characters are basically thrown away after a few chapters/story arc. Also, almost no character development. Like, cool, the character has multiple relationships, but why does the harem always have the character equivalent of a cardboard cut out? Make interesting characters that develop throughout the story, not more characters that have no use to the story except the few chapters they are introduced. I don't hate harems, I hate lazy writers.

I think considering the growth of industry, the complete domination of said industry, military might, political power, etc would make the buying power of the thaler to be significantly higher than some of the median income numbers you gave. It's not only backed by all that, but also by the giant and complex economy running right here, which is entirely dependant on the Empire's vast trade network. I'm not an economist but I would put it more near 1950's median income when adjusted for inflation, and considering the buying power to the thaler I wouldn't be surprised if it were significantly higher. Just think about what a slightly higher than average wage in 2019 could get you in terms of quality of life, things like education, healthcare, and housing. (And before you say anything about healthcare being a gov't service instead of private, you can consider that further investment into the population, so from a buying power perspective I don't think it would decrease in this case) Compare that to what a slightly higher than average wage in 1950 could get you, probably far more than a slightly higher than average wage in 2019. I think the quality of life here may be even higher for a larger percentage of the population here than for Americans in the 50's, although that might also be because of its inclusivity which has its own demerits that I won't get into. TL;DR I think the numbers are a little low.

Yes, I also think green-eyed would be appropriate here as it is a compound adjective.
