It's a spectrum. The OP's approach, with the wrong kid, could very quickly turn home into another (worse) school and wreck the kid for a long time. "Raise kids where they are," taken to the extreme, will teach a lot of kids to accept mediocrity.
"Dehumanizing" is extreme. Having goals and benchmarks is important, probably even required, to help everyone grow to their full potential.
