I visited my younger brother over the weekend who is getting a PhD in math. He introduced me to Usher. I had actually heard some of the artist's performances in the past, though I didn't know the artist's name.
It seems this musician has studied Rothbard. For example, he continually refers to "thugs in the club" in his poetry. I can only assume that this is a subtle reference to the employees of the US federal government, the biggest gang in the world.
Usher's economics acumen is clearly on display when he refers in a patronizing way to "Shorty," an obvious dig at economics professor and former Clinton Labor Secretary Robert Reich.
Bravo, Usher! I salute your keen insight as well as your gentlemanly discretion. Keep us guessing!
