I didn't realize McDormand sold her house because the company she and her husband worked for went under. I'm not sure if her hometown has declined or if others stayed while she decided to seek freedom by leaving her prefab home behind to travel across the USA in an RV.
If I recall correctly, she could have just chosen retirement. Regardless, American payouts are much larger than ours, so there's no reason to feel sorry for her.
Rudan says the movie portrays the beauty of poverty, and because of that, she finds the film distasteful (or something to that effect).
I don't see anything to complain about. It's her choice. She is simply a bit of a rebel—someone who has been more sensitive to injustice since she was a child (according to her sister)—which even leads her to clash with real estate speculators who exploit the basic human need for housing to drive up prices.
Fine. She decided not to be a slave to a house or property lines like Americans often are. Half of Germans don't even own real estate. Instead, they travel more and enjoy their money and experiences. Germans don't view owning property as the ultimate life achievement the way Americans do. For us, having an extra few hundred square feet matters more than seeing the world.
