Upside Down Flag

We dipped across the the US border for a day trip and found this flag, in a nice neighborhood, declaring that the country is in trouble. The upside-down flag is a sign of distress, recently brought to public attention by a Supreme Court Justice who displayed this orientation on his property. The juxtaposition of this perceived despair, with the reality of prosperity that this house demonstrates, and this level of paranoia is baffling. US flags on personal property are ubiquitous wherever you go in the States but this seems out of place for all kinds of reasons.
