Chattel slavery not only fueled the industrial revolution but laid the foundation for our modern world. Capital accumulation, investment of capital, private ownership of the means of production (people), high levels of wage (free) labor and efficient (non-paid) use of the factors of production (people) - are all mechanisms of capitalism that reach their maximum potential under the conditions of chattel slavery.
The whole point of industrialization was to replace human labor with machines and obviate the capitalist need to own slaves!
