That's because reading in schools these days is garbage. When I was in school, we read classics. Can't do that anymore, especially if it's stuff written by dead white guys. And yes, that's the case. My two younger kids brought home what they were reading and by-and-large, it was pure dreck. My kids thought so too.
OK, I'll start by echoing what Ironwing stated following your post.
In addition to what I just quoted, my younger daughter and son both complained that all they were reading was simple articles; nothing challenging. And it was a disproportionate amount of women / girl themed stuff - their words, not mine. My kids both thought the material was just preaching at them.
