Tbh I've learned that a lot of this time, this is because we're largely taught these days, as a society, to "mind your own business" or "focus on you". Or, they don't want to make their own life more complicated and/ or difficult by taking on that person's burdens too. Or, the bystander effect is a thing too, where people think "surely someone else will step in." Lots of factors here, many of the bullshit tbh.
