Depends on where you live, up until about 12 months ago I was in the same boat as some of you describe, so the wife and I packed up the family and moved to the Kimberley. Money is no longer a conversation topic, and I haven't checked the bank balance for months.
No, we're not in the mining game, just a teacher and a nurse, we just live a blessed lifestyle, without all of the city(east coast) trappings.
The kids no longer even want McD's or any other junk food, prefer fresh caught Barra, and all their electronic devices have been gathering dust and have been replaced with fishing rods and camping gear.
Life's good here
