Hi there, enthusiastic and regular Transferwise user here.

I think the answer is that while Transferwise is a great product, Western Union serves a niche that Transferwise/PayPal/Web Startups aren't fulfilling. That is anyone even with low income can just go into a store and use it. No need for a bank account, a PC (even basic computer knowledge is not required which may hinder older people) or the internet.

I don't know about everywhere else in the world, but these days it's not too hard to get a free bank account in either the US/UK.
