I don't think I have ever encountered anyone who could not write a for loop that got a job as a programmer.

I encounter plenty that used a for loop when something else would have been advisable.

> I think you have far more leverage than you think in most places still.

In some sense this is true, but in my view it's not whether a person theoretically has leverage or opportunity, but whether it's feasible to practice or to explore it. If enough people believe that programmers shouldn't have leverage, and in-practice if there's only negative repercussions from trying, then it's not meaningful. Broadly, in any profession, it seems like it comes down to a whole lot of luck whether you have real, practicable leverage. Barring some exceptions for somehow intentionally positioning oneself to be solely responsible for an uncommonly important system in an uncommonly lucrative business, but that seems to me to also be dependent on a lot of luck.

Overall, it seems that if you really have leverage, you effectively can't economically be replaced, and everyone knows it, but otherwise you'll be on the chopping block for not doing exactly what your narcissistic boss wants on a moment to moment basis.
