We are taught that achievement means value. Circularly, we value ourselves for achievements and we inculcate this in our children.

It is a value judgment. It's one that not everyone shares. It's surprising to me that a majority of people find it to be a controversial.

I think what's actually going on here in this thread is that people think any value judgment must be a bad thing. Right?

I'm not saying that any value judgement is a bad thing. I'm saying that you're viewing your upbringing strictly through the lens it handed you.

As far as I can make out, your argument goes like this:

Strict parenting is good because it produces high achievers. I think achievement is good because I was conditioned to think it was good. I was conditioned to think it was good as a result of strict parenting.

Effectively: strict parenting is good because I was strictly parented.
