I think this is nature's risk management mechanism at play. I believe nature has put a mechanism in our heads, which prevents the easy spread of global threats to humanity by dividing us (the society) to different subgroups. This division acts as a barrier for the contagion effects of different threats or at least slows them down significantly. Let's take for example the current Crypto sale. People who invested in crypto are losing money, but fortunately nature created other individuals, who think crypto is a scam and they've never put their money on the table. They are safe compared the their peers. An example, where this mechanism has been compromised by humanity is the civil aviation and the COVID spread. If we didn't have a sophisticated and integrated civil aviation industry COVID would have had a hard time spreading around the globe so fast. 100 years earlier and the virus would have needed many more months to spread. So, I think nature deliberately (or evolutionary) put a mechanism in our heads, where we try to protect our own group and harm the outsiders. This reinforces nature's risk management.
