Yes, it's always been about expections. I have the hour's commute although these days don't do it every day and I live in zone 5. That is not unusual. I used to work with law firm parnters who commuted from Brighton, Cambridge, Kent, Herts and that is decades ago. This is not a new issue. Which areas are most expensive and most grotty varies from time to time of course. My daughter bought ex local authority in zone 1. You just have to take your decisions if you're lucky enough to be in work and able to save up a deposit and live accordingly.
1954 : Betjamen was writing about "Elaine" commuting into London from Ruislip etc
"Middlesex
Gaily into Ruislip Gardens
Runs the red electric train,
With a thousand Tas and Pardons
Daintily alights Elaine;
Hurries down the concrete station
With a frown of concentration,
Out into the outskirt’s edges
Where a few surviving hedges
Keep alive our lost Elysium – rural Middlesex again.
Well cut Windsmoor flapping lightly,
Jacqmar scarf of mauve and green
Hiding hair which, Friday nightly,
Delicately drowns in Drene;
Fair Elaine the bobby-soxer,
Fresh-complexioned with Innoxa,
Gains the garden – father’s hobby –
Hangs her Windsmoor in the lobby,
Settles down to sandwich supper and the television screen.
Gentle Brent, I used to know you
Wandering Wembley-wards at will,
Now what change your waters show you
In the meadowlands you fill!
Recollect the elm-trees misty
And the footpaths climbing twisty
Under cedar-shaded palings,
Low laburnum-leaned-on railings
Out of Northolt on and upward to the heights of Harrow hill.
Parish of enormous hayfields
Perivale stood all alone,
And from Greenford scent of mayfields
Most enticingly was blown
Over market gardens tidy,
Taverns for the bona fide,
Cockney singers, cockney shooters,
Murray Poshes, Lupin Pooters,
Long in Kensal Green and Highgate silent under soot and stone."
