Some of the vulnerabilities are:
... Humans are far more mobile, globally, than they were in the '30s
... Supply chains are JIT (just in time) and are, again, more global. Most products are not produced locally and are not warehoused/stockpiled for the most part.
... Food chains are also very long, intercontinental in many instances. The onions in my stew last night are from Peru. I'm in North Carolina.
... Many products these days are not built to last. Planned obsolescence is a thing now.
... There are far more humans now, making more demands on systems. Per capita energy and resource consumption is much higher. Economies/jobs/infrastructures get locked into those levels of production/consumption.
... Systems are far more complex, optimized. A lot of things have to go right for them to perform.
... Financial and technical cross-contagion is more of a thing these days, IMO.
Yes the vulnerablility of complexity is real, and still to be genuinely tested.
Re food, I guess there aren't many countries left that could feed themselves if they had to. In NZ, which is a real food bowl, we couldn't these days because we specialise so intensively for export markets, mainly dairy products. Once, we had a very wide range of horticultural and agricultural crops including substantial wheat production, but farmers went where the money was (of course, and who can blame them?). We wouldn't have any bread if we got cut off, but we sure could stuff ourselves with 'milk solids'...
$this->bbcode_second_pass_quote('GHung', 'I') could go on, and folks are free to add to the list. I have to go buy more toilet paper
