Every white person who participated in the economy benefitted from suppression of competition of other races. You don't get to escape the benefit when the entire society is designed to exclude your competition.
That's a really inadequate zero-sum perspective. We can assume blacks to be just as talented and hard-working as whites, so including blacks into the economy and society should have grown the economy and wealth about proportionally. The pie would have to be shared among more people, but also grow in size. It's highly non-trivial to calculate which effect would have been larger.
Yes, certain low IQ/low skill whites would have been worse off if they had to compete, but the higher education whites would have benefitted from society tapping into the potential of blacks. All whites would also have benefitted from a more equal society, better race relations, less crime and government spending on police and prisons, and so on. For those unfit for meritocratic competition, the downsides of racial integration would presumably have prevailed, but for everyone else, Jim Crow was a net negative.
At the end of the day, the diverging economic development of the antebellum South and North prove that slavery or slavery-adjacent discrimination does not create sustainable wealth. In the long run, slavery or massive racial discrimination leaves everyone worse off except for a tiny few rich elites and a few low ability individuals from the privileged group.
Jim Crow did not make working- and middle-class whites rich, it made (almost) all of America poorer.
