This was a problem in the Great Depression, too, though the conflict was less between banks than between individuals who often issued or bought individual mortgages as investments. No good way to resolve the problem was found, and thus it is still with us. I'm toying with the notion that we should ban second mortgages by any except the first mortgage holder, but this would turn the first mortgagee into an effective monopolist, and also effectively kill securitization. Plus I don't know what you do with an insolvent bank if all the first and second loans have to be sold as packages.
Still, it would be nice if we could figure out something to do. We need to figure out how to resolve the housing mess sometime before the turn of the next century.
