Can happen everywhere. Wait what happens if you cut down food supply to a rich nation like for example the Netherlands. Within a week people will kill each other for food.
This does not only apply to the US, with the January 6. "insurrection", it even happened in places like Germany [0] and recently Romania [1].
It's a combination of entitlement, and 2 years of pandemic forcing many people, and their businesses, into dire economic situations.
Such dire economic situations can trigger regime change anywhere, completely regardless of "democratic institutions" or all these other nice sounding words.
Because most people don't really want that much; As long as they have a job that allows them to put a roof over their, and their families heads, and food on their tables, that long the vast majority of people couldn't care less if the government they live under is considered "democratic" or "authoritarian".
These are way too high and abstract concepts for the vast majority of people to care about. They are too busy with every day live, working to pay rent and getting food on the table.
But what happens if they don't have the work anymore to pay for rent and get food on the table? Then they will take to the streets, they will demand change, completely regardless of what kind of regime they live under.
Even the Roman Empire already knew this; panem et ludos
Give people enough bread and circuses, and they couldn't care less about what happens on the higher levels above them or how they are being wronged in rather intangible ways.

Still, we grow a very large amount of food, especially relative to the size of the country. We're the 9th largest potato producer [0] in the world, despite being a tiny country both population and size wise, because we have the highest yields in the world. Someone downthread linked a NatGeo article explaining more [1] but we have far higher yields, several times higher than any other country, on many crops, such as chilies, green peppers, cucumbers etc.
[0] the very helpful FAOSTAT is excellent for things like this: https://www.fao.org/faostat/en/#data/QCL

Presumably, per capita it's number one.
