Specifically, what you explained stoked the fire, but what poured gas on it and simultaneously kicked the embers about the room, was Rudolf Guiliani taking RICO to make his case against Mike Milken, actually first of all Mike's far more vulnerable brother was indicted, but that aside Guiliani forced Drexel to shut it's trading desks, which drained the market for the junk bonds which had allowed so many tiny thrifts to engorge themselves, and without any mark to market -the whole market consisting of Drexel making two ways all on it's lonesome (who else had a clue what was in those bonds?) - the multitude of vastly bloated regional S&L's couldn't post their accounts, and simultaneously all went belly up.
Not being funny, but Guiliani forced the whole mortgage banking business into insolvency to make a point that some still think was Vendetta. Whatever the case, Guiliani forced a vast capital market to halt, for no reason I've ever learned, and handed a four trillion dollar bill to the taxpayer, for kicks. No wonder Trump likes his advice.
