“Just realize that money market funds are NOT CASH”
I think the difference here is that we have a change to how money market ACCOUNTS in commericial banks,S&L’s are going to be restricted.
This is not the same as a fund handled by your broker.
Since the repeal of Glass-Steagall, the line between bank and broker has become rather blurred. Plenty of people now bank (or have checking accounts) with their brokers, and commercial banks play broker here and there, especially for retirement accounts.
