Switzerland superficially seem to makes it almost work, but it has strict linguistic territorialism for its 3 prestige languages. I wouldn't call it a real example of successfully making its native ethnic groups thrive though.

The smaller native languages, as always, got shafted and are declining into oblivion ( arpitan, lombard, jurassian, romanche, walser, alemanic, will go extinct in a few years / decades depending on how far gone they are ).

Even among the 3 prestige languages, French, Hochdeutch and Italian, French has been encroaching on previously alemanic territory ( rather than Hochdeutch taking that role ) and Alemanic + Hochdeutch encroached on Lombard ( rather than Italian taking over ).

Romanche is getting chewed like the other tiny languages mentioned above ( Lombard, Arpitan, Jurassien, Walser ), but much slower because its speakers had a much more sharp ethnic/linguistic consciousness. No Romanche speaker thinks they are inferior for speaking "degraded Italian" and should speak Italian and educate their children in Italian. Maby having Alemanic then Hochdeutch chewing their up rather than Italian spared them the "I speak degraded X" shame.

Speakers of the other tiny languages think they speak "degraded Insert Bigger Language Here, please assimilate my kids to that through school please".
