UBI goes to everyone and affects everyone. Who's the "everyone else"?

In other words, people who already have money would see that money devalued, perhaps very significantly and in excess of the new money they receive. I'm not terribly averse to the concept, but it would seem to be a redistribution of value that would significantly impact the wealthy. Which makes it tough to actually pull off, because they have a lot of resources to fight such a thing.
