Ostensibly, countries like Germany are competing to attract talent and investment, mandatory bureaucracy in a relatively obscure language is going to be a detriment to that.
A language spoken across Germany, Switzerland, Austria, Lichtenstein, and Luxembourg, parallel in weight to French across European countries, and in the old days the lingua Franca in Eastern Europe, which would rather speak German than English.
>lingua Franca in Eastern Europe, which would rather speak German than English
No we wouldn't. As an Eastern European I can assure most of my countrymen know and prefer English far better than they prefer and know German.
You're probably thinking of the countries bordering Germany that still have ethic German populations from the post-WW2 era, or the ones part of the former Austrian empire (Slovenia, Serbia, Croatia, Bosnia, Hungary, etc.) where learning German was mandatory during those times and the tradition of learning it in school as the main foreign language was kept till recently, but if you go a bit east, or look at youth of today, almost nobody speaks German compared to how many speak English.
If you go as a tourist to Slovenia, Croatia or Bosnia, and talk to old people, you're far more likely to get by in German rather than English, but if you talk to young people, it's almost the complete opposite, which is fascinating.
bureaucracy is not mandatory here. If you are clever you can entirely bypass it.
When I registered my German company the worst was to get an internet contract. Registering was done in one or two day. Internet needed more than 2 months.
First you don't need a notary.
Second you absolutely must not need to register a Gewerbe, as this will inherit the most costs. Check how your work is a "free Gewerbe" (eg. providing system IT services, opposite to application IT services).
Third, get rid of a tax advisor, if you care to read the tax laws and maybe a book. I only took a tax advisor in one of my early companies, and it was a massive pain and costly. Without I always managed fine, and survived many extra tax office checks.
Finanzamt and Elster is easy. Social insurance also, just a bit expensive.
GmBH is expensive, so just take personal risk and register a normal UG.
