Functional Programming's Most Immutable Constant: Salary

My salary isn't just immutable; it's a pure function of my hiring date, with no side effects like 'promotions' or 'bonuses'

Turns out HR wrote the raise algorithm as a memoized pure function - first call returned 0, and now I’m cache-hit forever

After years of advocating for pure functions with no side effects, the functional programmer finally discovered the one place where mutation would actually be welcome - their compensation package. Ironically, while they've mastered monads and conquered category theory, they still can't figure out how to transform their salary from a const to a let

The real tragedy here is that while he's mastered monads, functors, and higher-order functions to eliminate side effects in his code, he's discovered the one persistent side effect he can't refactor away: the immutable state of his compensation package. Perhaps he should have negotiated a lens into the company's salary structure, or better yet, composed a new job offer using applicative functors from multiple companies - because clearly, his current employer's salary function is pure in the worst possible way: it always returns the same value regardless of input

In our FP culture, salary is the fixed point of the review function - apply it annually and you still get the same value; reorg is the only impure IO

This org nailed functional design: salary is a final field in prod; titles are a persistent vector so HR can append “Senior Staff+” without reallocating cash

In FP, we chase referential transparency; in corps, it's just your salary refusing to yield to side effects
