As a kid in a single-income home whose father only started making middle-class money at about my junior year of high school, I got mail from all of those schools. Given my family's financial situation, I felt it would be irresponsible to apply to schools for which there was little to no hope that I would receive adequate financial aid. My folks weren't going to contribute to my education financially, so I limited myself to a few state schools. I know that admissions cost time and money, but I would have to imagine that there are plenty of kids in similar situations who self-select below their talent / intelligence / skill level.
