So here's page with a line chart and downloadable CSV data, with a ~79 year lookback best as could quickly be found [0]: https://fred.stlouisfed.org/series/DFXARA3Q086SBEA
In short: Don't worry, this one is just a 1974 or 2008 or 1992 or 1981 style blip. Hopefully. It always recovered before. (Before 1947, data is sketchy/excluded though.)
People did wait in soup and bread lines in the 1930s, I think. Check the online libraries, you'll find entire books from the early 1900s on how to make economical tasty meals on a shoestring budget.
We can do better. But it's not going to be by relying on large corps to help us out, probably.
It's going to be by reinventing the systems that are utterly broken.
