It's not really about equity, though. My mother wasn't an SAHM earth mother, she was just an ordinary working woman doing ordinary things, as my dad was an ordinary working man doing ordinary things. They met friends in the pub, went to barn dances, went to the Lizard on holiday...
They weren't avoiding anything, they were just getting on with their lives. Were they fully happy and fulfilled all the time? I doubt it, but again that's a modern ideal, and a very naive one at that.
My generation (I am bang in the middle of genX) still weren't really the 'gap yah' generation unless you were rather more middle class than I was.
I've done my fair share of travelling and a bit of LSD on the way, whilst still being married with a mortgage and job in my very early 20s. I couldn't afford to do it all on some big 'finding yourself' deal. We did it in bits. We didn't do things we didn't think we'd enjoy, because why would you waste time and money for the sake of it?
I wasn't (and am still not) stuck, trapped or avoiding anything. OK, I've never gone skiing or climbed a mountain, because I didn't want to.
It's impossible to experience everything. It's OK to find your 'thing' early on and stick with it. Those adventurous people still only do things they want to do, that interest them. Nobody is saying to them, 'but have you tried sitting at home reading a book'. That might be pushing them out of their comfort zone.
There have always been people who want to live different lives. I wonder why we find it so much harder to let people choose the life they want now, despite the fact that it's now easier to do. Why we must assume not wanting to rush hither and yon is some form of 'avoidance'?
Having choice means just that. And, despite what some people think, there's a lifetime to live. You don't have to cram it all into your 20s. My parents travelled a lot in later life. It wasn't any less of an experience for them just because it wasn't interrailing with a backpack on.
Let your kids be who they are. Yes, help them if they need a push, if they have expressed a wish for more, but don't let them feel they have to be something they aren't.
