Earlier quoted context omitted.
Top private US schools provide very good financial aid packages and are a very good choice for underprivileged students if they can get in. Schools in turn want such students for diversity and metrics.
> if they can get in. These questions are framed in the wrong way. The filter isn't cost, it's getting in, and people from middle class and poor families are at a disadvantage in terms of accomplishments.
Yes and no. In that there is correlation but probably not direct causality. For example, Asian middle and poor families seem to do fairly well in getting their kids to have the right achievements.
