The first settlers of Virginia were European serfs who became free men after it became clear that they could just run away from the lords so the British colonies in North America are fine.The colonization of the Americas is significantly retarded, as is therefore the evolution of capitalism and the industrial revolution. Without the slave trade, you have a very restricted productivity of cash crops and plantations that rely on indentured servitude and indigenous enslavement, both of which are unreliable sources of manpower. Without plantations, Brazil and the Caribbean do not develop. I’m no expert on Virginia, but I’d suspect the same. Without the significant income and profits from the colonial system, the investments and financial services necessary to kickstart industrial capitalism will also take far longer to materialize.
If slaves were the main reason for Industrilaztion it would be Spain and Portugal who would do it first not the British.I base my arguments on Eric Williams’ classic Capitalism & Slavery. I don’t have the data on hand right now, but Williams proves how profits associated to the colonial system financed early industry. It’s also worth mentioning that labor being cheap in the slaveholding colonies does not automatically translate to cheap labor in the metropolis or non-slaveholder colonies (although, as Marx showed, labor was pretty cheap indeed anywhere you looked). Williams also agrees with your thesis that industrialization ended slavery, which I’m skeptical of myself, but it’s not the issue at hand.
