I think you are assuming a lot from these statements. Perhaps the schools you attended didn't have the right faculty to teach you about the danger of assumptions? Comments made in a verbal interview are not necessarily able to be judged as indicative of one's ability to communicate in written format. Furthermore, the interviewee was clearly exasperated because of her experiences, and this may have also played a role. Additionally, not everyone who earns a degree will have perfect sentence structure. I know nothing about Kaplan, but your assumptions are unwarranted and arrogant.
