Sir Sharukh Got it Wrong

In explaining U.S. or West's financial fallout, even though he went to great lengths, talked of consequences and root causes as per his wisdom. But, as per Roger C. Altman he is not correct. Roger Altman was U.S. Deputy Treasury Secretary in 1993-94.

Sir Sharukh Irfan (Forman C. C. Univ.'s accounting professor) is of the view that this meltdown of U.S. markets was due to the collapse of subprime mortgage market in the United States and consequently housing prices collapsed and thus emerged the crisis at the surface. The same reason has been attributed by Altman, in his article in the latest Foreign Affairs magazine, as 'conventional wisdom'. And, as per Sir, that at the bottom the preceding reason lied, and naturally, it had various consequences.

While, on the other hand, Roger says:

"This is not correct [that crisis is due to collapse of subprime mortgage market and housing prices]; these were themselves the consequence of another problem. The crisis' underlying cause was the combination of very low interest rates and unprecedented levels of liquidity."*

Roger sounds more reasonable to me and especially the lethal combination he mentioned. What is your opinion on this issue? Please do share with us.
