This is because Asians, I don’t think really are interested in helping other Asians. I don’t know if it’s because “Asian” includes many of the other sub-groups like Chinese (mainland/taiwan/hk/singapore/malay/americanized/fobs/hawaiians/etc), Japanese, Korean, Thai, etc etc etc…and they all used to hate each other to begin with, but that’s how it’s been since forever. They also compete fiercely for the same opportunities, etc.
I knew someone who was a wealthy/Asian business owner and he was complaining that the Asian people don’t seem to want to help each other Asian people like Jews or possibly other races.
I just don’t think it’s in Asian upbringing and they didn’t have it done to them neither so the cycle doesn’t repeat. Most only help their immediate and extended families.
This is probably why you don’t see as many Asians, I don’t think playing with random kids, but with their family friend’s kids too.
