Hi,
I know we have a bad demographic here in germany with not enough young people to support the elder, but my save (not attached because neither xml nor txt is allowed as extension) has 100% retired people while still having youth etc. I think while maybe remotely possible with retired people owning a business it is kinda unrealistic having only retired people in a country.
Especially because 60,85% of those retired people are state employees…
Save is available on request 
Yeah I’ve been shown a save game with this already. Suffice to say that the next build of the game will tone down the ability for policies to boost retirement membership quite so much 
Why don’t you also implement a maximum percentage like so: 100%-state employees-whatever
Just to make sure that the values stay consistent with each other.
Indeed, this is not a bad idea, although it probably needs to be more involved than that, because also there are self-employed people, who are likely not to be (at least not directly) state employees… argghhhh!
