I can't speak for anyone else here, but personally this whole fiasco was the final kick in the ass I needed.
I'm not looking for the US to fix themselves so I can buy from them again, I'm looking to divorce them for good.
They'll probably pull back from the brink in the next few years. I will still avoid buying American.
They'll probably go through a period of rebuilding and political/economic outreach. I will still avoid them.
