For those who somehow missed it when growing up, “Atlas Shrugged” is a fantasy in which the world’s productive people — the “job creators,” if you like — withdraw their services from an ungrateful society. The novel’s centerpiece is a 64-page speech by John Galt, the angry elite’s ringleader; even Friedrich Hayek admitted that he never made it through that part. Yet the book is a perennial favorite among adolescent boys. Most boys eventually outgrow it. Some, however, remain devotees for life.

And Mr. Ryan is one of those devotees. True, in recent years, he has tried to downplay his Randism, calling it an “urban legend.” It’s not hard to see why: Rand’s fervent atheism — not to mention her declaration that “abortion is a moral right” — isn’t what the G.O.P. base wants to hear…

And the Ryan fiscal program clearly reflects Randian notions. As I documented in my last column, Mr. Ryan’s reputation for being serious about the budget deficit is completely undeserved; his policies would actually increase the deficit. But he is deadly serious about cutting taxes on the rich and slashing aid to the poor, very much in line with Rand’s worship of the successful and contempt for “moochers.”
