I think it actually is interesting if you’re going to call out humans as a species of animal!

All across species from unicellular to megafauna, from plants to fungus, you can find mechanisms used to defend an individual’s physical territory. Ants and bees from the same species will fight and kill others colony members of they stray into their territory. Bears will fight and kill other bears. Our closest relatives, chimps, will go to war with neighboring chimp bands.

Artificial borders are humans way of saying “this is my territory enter at your own risk”. The REALLY interesting thing is that we have established systematic exceptions to the behaviors we see in nature. “Ask us before you come and you can visit and be safe here from those that enforce our territory.”

The temporary nature is unique, many social animals will permanently adopt an outsider into their group on occasion, equivalent to immigration, but I’m not aware of any that have pre-agreed temporary violations of group territory.

Inflation isn’t high anymore. Price increases are back to normal.

Layoffs in the past year or two have nothing to do with the economy, most companies doing the layoffs are making more profit than ever, except maybe Boeing but that’s clearly not economy related. They just want more money. Had nothing to do with the economy.
