I'll make an addendum to my last post.  There's a psychological factor to consider.

In the last few generations, the population of the FSoA has never been as poor as the poorest in Gaza or Ukraine.  We haven't had existential level poverty here since the Great Depression, which ended with WWII.

In the following decades there was growth in per capita energy use and a better standard of living for all except for one segment left out, the black population.  They broke out in mass protest, civil disobedience and violence in the 60s.  It was resolved through socialization with the Great Society program of Lyndon Johnson.  Then everone continued upward until the 80s, when stagnation set in.  Since then, we have had and ever widening gap between the haves and the have nots.

We may not need to drop all the way to existential crisis for bigger levels of violence, the difference between the way the rich live and the poor do and the diminished expectations of achieving the "Amerikan Dream" may be enough to set it off while people still have enough to eat to survive.

However, food isn't the only  essential for survival, shelter is also.  The increasing amount of Homelessness right now is a bigger threat than food availability is.  As this class of people grows and becomes more visible, it will be harder to control with sweeps of tent cities and mass shelters and concentration camps.  That is probably where the violence will break out first.
