That higher privilege applicants (of any race/ethnicity) have an advantage over others in admission to the most selective private colleges is not (or should not be) news. The effect extends beyond direct admission preferences for unearned privilege-correlated aspects like legacy to the fact that parental money tends to be used to improve opportunities and remove barriers when kids try to earn their merit.
Of course, many people also tend to have a view of privilege versus disadvantage that views those of higher SES than themselves as having what they see as undeserved privilege, while denying that those of lower SES than themselves tend to face more disadvantages and barriers than they do. The common tendency of the self described “upper middle class that does not get college financial aid” or “donut hole” (approximately the top 5% except the top 0.5% income and wealth) resenting both the higher and lower SES on these forums is an example.
