One other thing I'd add is for a lot of these ppl the "expenses breakdown" is different from the typical suburban population. They don't place too much emphasis on the actual house being up to par with their "class" - but if you'd add up all the "toys" they own and spend significant sums of cash on - GUNS, ATVs, tractors, snowmobiles, boats, bikes, GUNS, hunting and fishing gear, GUNS etc - if you add all this up we're talking being able to afford a much better house.
I'm curious why the emphasis on guns... Have you looked at the relative prices of these "toys"? You can buy a helluva an arsenal for the price of one ATV or tractor or snowmobile or boat or motorcycle. Shooting shit is actually one of the cheaper recreational pastimes in rural areas, especially now that the run on .22 LR ammunition is pretty much over.
And they do add up - an "average" household from the likes I'm talking about would typically have 2-3 diff caliber hunting rifles, maybe a bow, a 12 and a 20 shotgun, a 22 (typically one per member of the household - rugers for the kids, henrys for the grown ups :) ), not always but almost always an AR or Mini14 or an AK.
Then there are the handguns - there would be at least one but most of the time there would be an assortment - a 9mil, something more high powered like a 40 cal glock or a .357 revolver, maybe a Kimber 1911 but that one is optional :)
All of that adds up, especially with ammo. Which, after the shortages few years back ppl are still stocking up. Not like they used to, but more like - go buy a fishing lure and if the price is right pick up $100+ worth of ammo.
But, the folks I'm speaking of don't own the land their house is parked on, even if they own the house itself. It's a difference of degree rather than kind, I guess, but a pretty big one nonetheless.
