One of the least examined assumptions in the reparations debate is the direction of causation between wealth and slavery. The standard narrative implies that slavery created wealth: that British families got rich because of the slave trade, and that their descendants carry inherited wealth whose ultimate origin was the exploitation of enslaved Africans.
The causation actually ran the other way. To invest in the slave trade or plantation ownership, you had to already be wealthy. Buying a ship, financing a transatlantic voyage, and purchasing and running a Caribbean plantation required substantial capital at every stage. These were not activities that a person of modest means could enter. The barrier to participation was high. The slave trade was an asset class for people who already had assets.
A Bristol merchant who invested in a slaving voyage in 1720 did not become wealthy because of that voyage. He was already wealthy enough to finance it. His wealth preceded his investment in slavery. The slave trade was one of several things he could have done with his capital, and like any rational investor he chose it because the returns were attractive.
This brings in the second part of the argument. If that same merchant had not invested in slavery, he would have invested in something else: domestic trade, land, manufacturing, financial instruments, or colonial ventures unconnected to enslaved labour. The capital markets of eighteenth-century Britain were sophisticated and offered many opportunities for wealthy investors. The evidence strongly suggests he would still have grown his wealth substantially. His descendants would still have inherited significant wealth. That wealth would simply have a different origin story.
This matters for the reparations argument in two ways.
First, it undermines the claim that current wealth held by descendants of the merchant class traces to slavery as its source. The source was pre-existing wealth. Slavery was one deployment of that wealth among many possible deployments. Removing slavery from the picture does not remove the wealth; it just reroutes it through a different investment.
Second, it further narrows the pool of people with any coherent inherited liability. Entry to the slave trade required pre-existing capital that the vast majority of the British population did not have. The labouring classes, the minor tradespeople, the tenant farmers, the village craftsmen: none of them had the means to participate even if they had wished to. The trade was conducted by and for a narrow wealthy elite who were already distinguished from the rest of the population by their capital before they ever invested a penny in a slave ship.
The reparations campaign asks all of us to pay. But the people who actually invested in slavery were a small, already-wealthy class who would have been wealthy regardless. Their descendants may hold inherited wealth, but that wealth does not originate with slavery. It originates with the capital those families already possessed before the first voyage was ever financed.
