The Cost Effectiveness of Web Developers

I don't know about the salaries of native cross platform developers. But one other thing I want to throw in on this though is that if I am already building an application with either a node backend or a web component, then I have somebody that I can more easily repurpose to something like React Native or Ionic. And so there's that too. Right? So basically what you're saying is that web developers are cheaper and more plentiful than native developers. Maybe it is usually more cost effective.
