I disagree.
If the bank cannot get investment from other places, there might be a reason for that. ‘Bad’ investment.
The lack of capital is most of banks problems, due to the MBS’s...which US govt was going to buy..but they are also time consuming to sort out and sell...I like the stock option, and think it is much more a ‘free market capital’ solution...it is good idea, along with some purchase of the MBS’s.
