Refinery vs. Desalination Plant: Which Model for Building Wealth?

This question about engineering a wealth-building process really caught my eye. I work as a tailor, so I’m used to thinking about precision and process, and my hobbies in marine biology and geology make me see interesting parallels in systems like these.

A refinery takes something already valuable, like crude oil, and through a complex series of steps, extracts and purifies its highest-value components. It’s about optimization and maximizing return from a concentrated resource. On the other hand, a desalination plant processes a vast, abundant resource seawater to extract a universally vital but less concentrated prize: fresh water. It’s more about consistent, scalable extraction from a common source.

So, which feels like a better metaphor? Is building wealth more about refining and optimizing a specific, high-potential asset you already have? Or is it about developing a reliable system to draw value from a broader, more accessible base, even if the yield per unit is smaller? I’m curious to hear how others picture their own financial strategies in these terms.
