Why did Ayn Rand and Emma Goldman develop such divergent political views?

Ayn Rand and Emma Goldman had some striking similarities. Both were born in Russia, saw the rise of communism, and then fled to America. Both espoused ethical egoism and individual liberty (they both explicitly held the 'pursuit of happiness' to be the most important thing about American culture). But there was one crucial difference: Goldman advocated anarchism and the abolition of private property in the means of production, whereas Rand supported laissez-faire capitalism. What lead Goldman to hold such different political views from Ayn Rand?
