Are you the least bit aware of what caused the egg shortage? There was a super virulent strain of avian influenza (bird flu) that has the potential to infect wild birds and to jump to mammals. You know, like people. The same thing triggered the pandemic in 1918 that killed anywhere from 1% - 5% of the world population.
So to avoid that happening again, they had to destroy (slaughter) millions and millions of egg laying hens, which yes, caused a shortage of eggs relative to normal.
There are real issues that need to be addressed with capitalism and workers rights. This isn't one of them and you hurt the real arguments by not educating yourself.
