The link between Enlightenment values and imperialism/subjugation of Asia/Africa/Americans is far from clear. Enlightenment values aside, conquering people and taking their stuff was just normal at the time. And while imperialism enriched certain people and led to economic growth, it was probably worse from a economic-growth-first perspective (compared to free trade and sovereignty).
Along the same lines, American slavery was highly profitable for some but there is no good argument that it was essential to the US's economic development. Paying workers supports economic growth by increasing productivity and demand.
Over time, this project of attacking the enlightenment/liberalism has started to seem increasingly boring and wrong to me. For one, the vast majority of these critiques rely on Enlightenment values to critique the Enlightenment. So maybe we should be more enlightened! For another, right-wing populism makes liberal capitalism much more attractive.
