It’s more difficult to gauge the income of other people than you think. Do they own their home or are they renting? Did they get family help to buy in a good neighborhood? Have they been there 20 years when the costs was a fraction of what it is today? Do they put their money in cars but live frugally in other ways? Do they support other family members?
Most kids don’t really know their parents income or are given very generalized info. Many kids are uncomfortable telling others what they do know. I can say we make a lot less than 200k and we got 1050 from UCSD. Unfortunately, It’s not likely a mistake that you didn’t receive any aid. More than likely, the people you are hearing about make less than your father does.
