The alternative to new competition (which would probably also raise its rates as soon as it became popular enough) is regulation on the fees, as seen in Europe. This makes some sense as the problem is less with the capabilities of the systems which exist today and more with the size of the fees of established players. I don't see the US going down this route any time soon though.
Most likely, in my mind, is the world (and maybe eventually the US) moves away from US based solutions in this space over the coming decades as other governments continue to consider this something to act on.
