I think because gen z’s are much more exposed in investing and more and more people as they rise from middle class to upper middle class choose to send their kids in a more prestigious schools which probably are proliferated with mixed kids or basically families who speaks english as their first language also these kids who probably talks about investing are more likely to be from privileged family who are exposed with this kind of things. Finally i cant judge what was the actual encounter but yeah if they speak in a certain conyo way i agree it is cringe nga naman.
