Mavericks owner Mark Cuban is throwing tantrums all over the internet over DeAndre Jordan's decision to back out of an oral deal and re-sign with the Los Angeles Clippers for roughly equal money. (NBA salary money is not real money, and then you get into state income taxes and the sorts of insane clawbacks that numbskulls like Scott Walker are trying to implement and, well, forget it. Suffice to say that the Jordan family will probably be doing just fine for a long time regardless.)
Mavericks owner Mark Cuban is, in essence, mad at Jordan for being selfish and not honoring his oral agreement.
Mavericks owner Mark Cuban is a huge fan of libertarian doorstop manufacturer and author Ayn Rand.
One of Rand's best-known works (besides "I will bang your much younger boyfriend because Philosophy") is entitled "The Virtue of Selfishness".
Suck it, Mark Cuban.
