When should parents stop paying for their kids?

[immense]

In every sense. So when should they demand rent etc? Should they ever or should they let their children leave the 'nest' as and when they're ready?

Very relevant to me atm!

[Special]

when their children are on a comfortable wage

[flatface]

After education (such as uni etc) when the "kid" is stable and earning

When they chose to. My parents won't demand rent.
