Do you watch Little People, Big World -- does it seem like reality TV is destroying families?

I don’t watch this show religiously, but there have been a few episodes on today & I’ve been watching. I have no idea what season these episodes are from buttt I think they’re recent (older boys are seniors in high school). Does it seem like the two parents are about to split up? Is this what happens when families go on reality TV? Can you think of an example of a family or person that has thrived from reality TV?

I watch lots of TV but not lots of reality TV… but it seems, to me, people who are signed up for this are doomed.
