There's a property in Panama where Trump has collected somewhere around $30 million just from selling his name to this property - it's somewhere between $30 million and $50 million. It would be so easy for a developer to slap on an extra $6 million to a Trump licensing deal and have that be a backdoor bribe. Who are we to say what that is worth? It's so ephemeral. And this is the appeal of selling something as ephemeral as a brand name, is that it can be inflated beyond all reason.
