Adults don't. Closest you can get is date someone who wants to help you out.

That's not universal, though. Many children are neglected to various degrees, and my understanding is they'll still work out their language if they get adequate exposure to it.

You probably only need a tutor the master the intricacies of the more prestigious registers, but that's a different thing than fluency.

Also: children whose parents immigrated.

The parents may never end up learning the language of the new country, but their children often will.
