Sorry--by "striver" I just mean a district with a lot of wealthy parents who think their kid is a special snowflake, etc. That is, the teacher's thinking might be that if one child is reading books above grade level, they will all want them reading War and Peace, or something, to prove how smart their kids are? I don't really know (I feel like such parents are just as likely to complain about books that are too hard), but this seems to be a concern in some areas.
