Whether or not anyone thinks standardized tests are biased is actually irrelevant because anyone who thinks college admissions should be based on a simple formula of test scores and GPA either has no concept of how colleges and universities work or are on heavy pharmaceuticals, or both.
First of all, doing that would absolutely kill competition. Second, students have so much more to offer universities other than test scores and grades. Elite schools do and will continue to look at the whole student because a school full of book nerds with no social skills and no ambition to do anything other than study creates a place that no one wants to pay hundreds of thousands of dollars to attend. Even the most elite schools, Harvard isn't one, like MIT and Harvey Mudd sell student life to prospective students. These schools, again more than the Ivys, absolutely care about academic accomplishments, but as a means to judge that they're up for the rigor, not as a sole means for admission, that's crazy and there isn't an admissions office in America that would actual want that.
