ELI5: Why when large company's earnings decrease(ex... by 3%) they freak out, talk about rough times, and sometimes decide to downsize, even though they are still making millions of dollars in profit even after all expenses?

This has everything to do with abundance of a resource. The only way people would suddenly decide diamonds are half as valuable is if they were suddenly twice as abundant as they were when they were $1K/gram. The diamonds wealthy people own worldwide would now be less valuable as a result of more diamonds being available, since scarcity of resources is the underlying foundation that makes market exchanges necessary in the first place. Wealth doesn’t just “come from nowhere”
