I have colleagues that commute over an hour each way to get to work, just so they can have a back yard. It is a bit different when you have kids though. I live 20 minutes walk from work on a post stamp sized section, but I wouldn't raise kids where I live. Too many heroin addicts and not enough open space.
If you're a blue collar worker, you can usually find a job near where you live. If you're a white collar worker, you need to find a house near where your job is.
If you're a tradie in Melbourne or Sydney, you can live in the suburbs and find a job in the suburbs. But all the tech workers are stuck working in the city, so you either spend a literal fortune on a house nearby (buying or renting are both expensive), or have a massive commute.
It does give me pause for thought. I'm nowhere near close to settling down or having kids (not that I have any desire to), but if it does happen, I'm not sure what I'd do. Commuting for an hour each way doesn't sound like my kind of lifestyle.
