While Kennedy didn't get around to passing any legislation himself before he met his untimely demise, the Civil Rights Address did provide the lightning rod for LBJ to get the kind of traction he did on the Civil Rights agenda after JFK's death.

The core thrust of his speech is simple: it's abominable that the nation's Black citizens are denied any real chance of prosperity and success in the United States, and it's tone-deaf and lacking any sense of justice for people to ask them to kindly wait their turn.

Most importantly, he commits to demanding Congress that they back him on this play. This urge, so close to his own death, must have echoed in the back of Congress' mind in the days of mourning to follow. In proposing and passing the Civil Rights legislation, Congress was making good on JFK's request in this speech.
