Essentially, the dissolution of Glass-Steagall allowed investment banks to create complex financial packages, each one constructed out of dozens if not hundreds of home mortgages. Each individual mortgage was graded but the packages were built out of a mixture of low-grade and high-grade mortgages. Since trading (gambling) with these packages was very lucrative, the investment banks worked with shady mortgage brokers to increase the number of packages by pushing adjustable-rate mortgages on gullible people who probably were not that familiar with compound interest calcululations. These unlikely-to-succeed mortgages were mixed in with the high-qulaity mortages to create a wide variety of highly leveraged financial products, and then bets were placed on the outcomes of trading in these products (derivative markets, synthetic CDO squared nonsense, etc.). Once people realized that many of these mortgages were not going to be paid off, then the avalanche of collapse began.
Glass-Steagall, if retained, would have made all of that impossible.
