A detailed blog post on the philosophy of Ayn Rand at the Rotman Institute:
For many on the left, the sub-prime meltdown, financial crisis, and ongoing recession are proof positive that the laissez-faire, deregulatory approach is dead in the water. Rand’s followers have drawn the opposite conclusion: the crisis is the result of too much interference and the failure of governments to fully implement the measures they propose. Going half-way, the argue, simply will not work.
In this they may be right.
