Also, if we wanted to go back even further, the true roots are probably the Enlightenment. Before Wilkinson and Watt and Darby could think to develop technology, they needed certain political rights that didn't exist to previous humans. The rights to privately acquire land, create corporations, sell across markets - things that lay people didn't have access to in earlier eras. And most importantly, courts that would enforce said rights for you!
And they needed double-entry bookkeeping! Perhaps one of the most underrated human inventions of all. Your wealth was no longer determined by how much stuff physically hoard, but by a record of entitlements.
