The financial situation of JWs in the US varies greatly.
The US has extreme differences in economics from city to city, city to rural areas, and especially from State to State.
In our old circuit in the Midwest USA, there are families that are millionaires and live in a homes worth nearly $1million. They are the extreme exception. Only a small percentage of all homes in this area sell for close to $1million. They owned a successful business before being converted into the religion.
There are also families that live in a used mobile home that cost $1000-$5000 to buy, plus $200/month rent for where they park the mobile home in a mobile home court. They are also exceptions. Most people in the community, and most JWs do not live this humbly.
There are also those that live in a 2-bedroom apartment that pay $700-$800/month rent (plus utilities). Especially young couples start off this way.
The "average" person in our former congregation has a 3-bedroom house (probably most are still paying a mortgage) that is worth $100,000 to $200,000. In most middle class families the husband and wife both work (at least the woman works part time cleaning homes) and they are earning $50,000-$100,000 annually. Most of the men are blue-collar workers, typically construction work. In major midwestern cities these jobs are still Union Jobs and it is typical to earn $50,000 annually. Carpenters. Plumbers. Electricians. Welders.
However, in much of the metropolitan areas of the East or West Coast, a house costing $500,000 to $1million is not that unusual, though still not average. So, the variety of comments vary so greatly depending on the region of the US, and if it is a metropolitan area or rural area.
I also think the average JW has changed drastically in the past 20 years. Most are no longer sacrificing as did their parents. They are both working, they are buying nice homes or building new homes, they have 2 nice cars, and most are taking vacations, some very nice vacations. Although the US citizen is not getting 6-weeks vacation time like much of Europe seems to get. More than one or two weeks vacation is very unusual in the US. Many do not get a paid vacation but must take the time off without pay.
BTW -- I assumed that the wealthy JW family in the video was probably depicting a materialistic family that had not been living with the right priorities in their lives. Is that not the case? I haven't had the opportunity to see it, and not sure I'm really wanting to run right out and do that anyway.
