That does not appear to be a debunking so much as a smearing. It'll take more than calling something plutocratic for me to see problems with it, and as far as I can tell they just quote a bunch of libertarians and expect us to be offended that they make sense.

It is not the fault of the industrial revolution that subsistence agriculture pays poorly. That is the fault of subsistence agriculture. It is the fault of the industrial revolution that factory work pays well, that factory owners gets a return on their capital, and most of all that consumers benefit.

You can look at wage data in England if you don't believe me- the primary beneficiaries of the Industrial Revolution were unskilled workers and consumers. (The last place I saw this data collected was A Farewell to Alms, but I imagine there are other more focused sources).
