I think what's particularly insidious about this article are the underlying assumptions. To understand why it considers the results of the study it examines striking you need to conceptualize society in a strict hierarchy. The wealthy and intellectuals at the top who are above things like racism, sexism, and the like. And the bottom, with the lowbrow and ignorant commoners who are susceptible to such things. The essential assumption is that those at the top are too good for these disgusting opinions, when most reasonable people know that's not the case.
Ultimately, this goes back to the marketing that made racism "unacceptable" in the United States. It's crime, is not being unjust, it's being common. The flaw of the poor, uneducated whites. The proper response, of course, is to dilute every culture and ethnicity, through capital, into being pseudowhite torch bearers of the cause of liberalism.
Don't forget the possibility of refusing to identify yourself. Without an identity there is no way to bill you. So you just leave and the hospital has no way to contact you. This is the path taken by many, especially the poor.
