But Maybe She's Changed Her Mind

From Elena Kagan's senior thesis for Princeton, TO THE FINAL CONFLICT: SOCIALISM IN NEW YORK CITY, 1900-1933:

The story is a sad but also a chastening one for the who, more than half a century after socialism's decline, still wish to change America. Radicals have often succumbed to the devastating bane of sectarianism; it is easier, after all, to fight one's fellows than it is to battle an entrenched and powerful foe. Yet if the history of Local New York show anything, it is that American radicals cannot afford to become their own worst enemies. In unity lies their only hope.

And Kagan dedicates her thesis, in part, to:

Finally, I would like to thank my brother Marc, whose involvement in radical causes led me to explore the history of American radicalism in the hope of clarifying my own political ideas.

It never seems to have occurred to Kagan that socialism has failed, not from external factors, but from its own singular lack of merit as a viable political system.
