I was waiting for the punch line as well, and then scrolled up to see who the author was. His tagline says, "I defend laissez-faire capitalism, using Ayn Rand's Objectivism." So it's safe to say it's not satire.
That shouldn't stop you from finding it hilarious though.
He does say "Here’s a modest proposal".
I think the author just stumbled hilariously onto that phrase without knowing its satirical history.
