The far right national government certainly isn’t good, but you’re right that it’s probably not that far off from most other big european countries right now. Definitely research the specific region you’re moving to, there are often extremely large differences between regions in european countries when it comes to political leanings, general tolerance and economic opportunities and it’s not always as clear-cut as “big cities good, countryside bad” or “north good, south bad”.
In a lot of ways, our current way of living has made us more resilient. Malnoutrition, frequent serious diseases and a high amount of environmental and food-borne poisons (soot, heavy metals, the snake oil that often passed as “medicine” back then) don’t make people stronger, they make them weaker. Our civilization diseases like obesity and allergies are their own issue, but they still beat dying from syphilis or influenza at age 30.
As far as propaganda goes, they had plenty of propaganda as well - it might have been cruder than today, but they also had less access to dissenting voices.
The health trend is definitely pointing downward in places like the USA, though. Let’s hope most of Europe can avoid the worst of that …
First we’d need to define “internet” for this purpose. Does classic mail qualify? It certainly can carry more data than pidgeons, and if you can still have computers you might get relatively close to the 90s internet by sending data by mail (especially when you’re communicating with people within a day’s travel, rather than on the other side of the earth).
Other than that, you can do a lot with visual signals. In the Discworld novels, they developed a kind of optical telegraph network with a technique that is somewhat similar to ship flag communication, and optical telegraphy exists/existed in the real world, too, though it never got much traction. If you have computers, you might be able to get pretty alright data rates with something like that.
I’d make it a point to not invest anything in the US, anyway.
