GDP/Capita isn't median income (it should roughly correspond to mean income); many of the higher GDP/capita are also higher inequality and so lower median is quite possible.
Okay, I already ceded that point anyway. The overall point that you can cherry pick to make any country look bad in one way or another stands, however.
Regardless, I'm happy to cede this point as it's irrelevant to the topic I was discussing: Cuba isn't that poor compared to its peers.
