Who is most likely to display arrogance, disregard for others, and an inflated sense of self-importance? I'd say it's some KOLs. Especially those who suddenly get rich—make a fortune and go absolutely crazy. This money doesn't need to be A9 or A10 in scale; as long as it exceeds their psychological expectations and ability to manage it, they quickly become vulgar, bloated egos, and start putting on airs. These types are small vessels easily filled to the brim; you can't offend them because they hold grudges extremely well.
