How did presidential addresses and supreme court rulings begin to change the lives of the american people beginning in the mid-20th century?

 Google some big ones, like: 

Brown v. Board of Education (integrated schools) 
Roe v. Wade (legalized abortion) 

A presidential address to look into would be President John F. Kennedy's “Inaugural Address”. His election represented a movement of youthfulness and promise in an America facing a turbulent decade.

I hope my answer has come to your help. Have a nice day ahead and may God bless you always!
