I’d argue this could embedded into an existing math curriculum instead. Most people could use this more than an advanced algebra class.
I found it much more interesting to study things with practical implications, and I also think embedding financial literacy into maths might be a good idea.
I'll add that I did of course eventually find uses for some of the things I was taught in maths class: path finding algorithms for a game AI, neural networks, genetic algorithms, all sorts. But in class, I didn't know any of these uses.
