I know of some dubs in construction who are struggling a bit, but they have their own networking system in place...dubs referring dubs referring dubs, so when a project becomes available, calls go out to each other to get them involved. A couple of brothers who did the same kind of work have pooled their efforts and have basically merged thier operations into one in order to survive.
I do know one brother who had to let his permanent help go but still needs help from time to time so he hires teens from the hall a couple of days at at time. He can pay them minimum wage (if that even) and only uses them sporadically so they don't bug him about needing more hours. Meanwhile the brother he let go is still looking for work.
As for dubs losing houses, I haven't heard of anyone being foreclosed on, though I do know of a couple who have their houses up for sale, just wanting to get out from under. They're losing money if they sell because the values fell but they see the Big A coming and they think it will only get worse.
But there are a couple of brothers who are in the buying business. They've actually gone out and bought up. They knew this was the time to get more house for the money. Apparently they're not as worried about the Big A.
Amazing what you can learn by just sitting and listening to JW family gossip about the goings on at the hall...
