I can sort of understand this viewpoint, but there may be reasons why someone may not have Open Source software on their resume. I have worked in finance, and I am currently working on my Master's degree in financial engineering. A lot of finance-oriented companies highly value their code. Now, yes, there are projects like QuantLib someone can contribute to, but if you someone was hired directly out of school and had never contributed to Open Source, chances are you aren't going to find any Open Source projects associated with that person. That person's employer probably doesn't allow it. With that said, the other case may be that they simply don't have the time to work on anything outside of work. Again, Wall Street is like this.
