I believe some disadvantaged groups are defined the way you describe. But, consider that black people, for example, harassed or even shot and killed by police because of the color of their skin, regardless of their academic performance, income, etc. There are plenty of studies and articles out there on the effects of systemic racism if you are interested. I do agree that we can do better in acknowledging and enacting policy to recognize and minimize the difference between economic classes.
