I was postulating why we are in the current mess, and my research has led me to the above act. It was repealed Nov. 12th, 1999 "by the Gramm-Leach-Bliley Act, which passed in Congress with a 343-86 vote in the House of Representatives, before being sent to conference committee; the final bipartisan bill (Senate: 90-8-1, House: 362-57-15) was signed by President Bill Clinton."
"The argument for preserving Glass-Steagall (as written in 1987):
1. Conflicts of interest characterize the granting of credit – lending – and the use of credit – investing – by the same entity, which led to abuses that originally produced the Act
2. Depository institutions possess enormous financial power, by virtue of their control of other people’s money; its extent must be limited to ensure soundness and competition in the market for funds, whether loans or investments.
3. Securities activities can be risky, leading to enormous losses. Such losses could threaten the integrity of deposits. In turn, the Government insures deposits and could be required to pay large sums if depository institutions were to collapse as the result of securities losses.
4. Depository institutions are supposed to be managed to limit risk. Their managers thus may not be conditioned to operate prudently in more speculative securities businesses. An example is the crash of real estate investment trusts sponsored by bank holding companies (in the 1970s and 1980s).
The argument against preserving the Act (as written in 1987):
1. Depository institutions will now operate in “deregulated” financial markets in which distinctions between loans, securities, and deposits are not well drawn. They are losing market shares to securities firms that are not so strictly regulated, and to foreign financial institutions operating without much restriction from the Act.
2. Conflicts of interest can be prevented by enforcing legislation against them, and by separating the lending and credit functions through forming distinctly separate subsidiaries of financial firms.
3. The securities activities that depository institutions are seeking are both low-risk by their very nature, and would reduce the total risk of organizations offering them – by diversification.
4. In much of the rest of the world, depository institutions operate simultaneously and successfully in both banking and securities markets. Lessons learned from their experience can be applied to our national financial structure and regulation."
It was finally repealed with the leading of Citigroup.
"The banking industry had been seeking the repeal of Glass-Steagall since at least the 1980s. In 1987 the Congressional Research Service prepared a report which explored the case for preserving Glass-Steagall and the case against preserving the act.
The repeal enabled commercial lenders such as Citigroup, the largest U.S. bank by assets, to underwrite and trade instruments such as mortgage-backed securities and collateralized debt obligations and establish so-called structured investment vehicles, or SIVs, that bought those securities.  Citigroup played a major part in the repeal. Then called Citicorp, the company merged with Travelers Insurance company the year before using loopholes in Glass-Steagall that allowed for temporary exemptions. With lobbying led by Roger Levy, the "finance, insurance and real estate industries together are regularly the largest campaign contributors and biggest spenders on lobbying of all business sectors [in 1999]. They laid out more than $200 million for lobbying in 1998, according to the Center for Responsive Politics..." These industries succeeded in their two decades long effort to repeal the act."
More stuff to read from the research.
"The second Glass-Steagall Act, passed on 16 June 1933, and officially named the Banking Act of 1933, introduced the separation of bank types according to their business (commercial and investment banking), and it founded the Federal Deposit Insurance Company for insuring bank deposits.
Literature in economics usually refers to this simply as the Glass-Steagall Act, since it had a stronger impact on US banking regulation.
Impact on other countries
The Glass-Steagall Act has had influence on the financial systems of other areas such as China which maintains a separation between commercial banking and the securities industries."
I will continue to read and find more stuff, maybe you, the public, can help me out.
