It seems to me that a lot of modern "white privilege" discourse has a very zero sum orientation. In other words it seems like some progressives assume that if black people are made better off then white people must be made worse off, and so whites have to give up their "privilege" in order for black people to have equal rights. While this isn't explicitly stated it seems to be implied by the framing of a lot of this type of discourse.

But is that true? Were whites made worse off by, for example, the passage of the civil rights act? The civil rights act obviously gave black people more job opportunities, but does that mean white people in the south now have fewer job opportunities than they otherwise would? I would think that allowing millions of black people to more fully participate in the economy would in fact spur economic growth and create jobs. Is that what happened or no? Are there any papers on the economic impact of the civil rights act?
