This is a bit of an odd question.

Ember.js is a tool like many others. So it's sort of like asking "Will I be richer if I learn Django or if I learn Rails?". Nobody on HN can really give you a definitive answer.

It is a framework for building rich javascript client web apps and helps you keep your code structured in a certain way and takes care of a great deal of boilerplate heavy lifting for you, if you take the time to learn it's idioms.

So the question, "Is there a way in which I can leveridge the fact that such a framework exists in order to make more money as a consultant?" is one that only you yourself can answer.
