Life isn't zero sum. If you look at the state of civilization now vs 2000 years ago, it's clear that we've played enough positive-sum activities to create much more wealth for the average person.
Much of the rise in prices has occurred in January and February. Seems likely to me that culling has continued due to bird flu and production has dropped.
I would also guess that demand is fairly constant for eggs, so large changes in price are needed to deter a small number of consumers from buying (low elasticity of demand).
"rebuilding" a laying flock is a fairly quick change, if the infrastructure is already there.
At a previous job we manufactured fairly large trailer-mounted generators. During design engineering testing, you would want to power a load with the generator to check performance. The test load we had was a giant resistor bank, in a pallet-sized enclosure about 4 feet tall, with fans for active cooling of the oodles of resistance heat being put off by it. I talked to one of the electrical engineers about how ludicrous this device was, and he said that we used to use something even weirder. A giant tank filled with salt water (can't remember for sure if they were using NaCl or a different electrolyte) with probes just dumping all that current right into the water. Wish I had seen it.
Any inventory warehouse can choose how much inventory to stock. If it maintains, say, 1 month of monthly demand instead of 3 months, it is more likely to run out of inventory during a supply chain shock. The fragility of the system is more related to this aspect than to anything else.
In the USA the EPA will fine you for intentionally venting refrigerants to the atmosphere instead of using a refrigerant recovery system for recovery/reuse/disposal.
I think that when people are jealous of others, they cloak this motivation.
To give an example with interpersonal relationships- never in my adult life have I encountered an adult who freely admits that jealousy is their motivation for attacking the reputation of a friend, but it happens all the time.
