Did mass produced goods like furniture displace handcrafted artisan goods? No.
In its heyday, between in the late 19th century and early 20th, there were about 30,000 people employed in furniture making in London, mostly in small workshops around Shoreditch, extending into Hoxton and Bethnal Green (where my mother is from as it happens).
Shoreditch serviced mass markets in London, the UK and across the globe, and while elements of mechanisation were introduced, the businesses remained essentially artisanal, centred around craft-based skills, with supply chains reaching deep into the local community via home outworking. Scale of production was achieved less by Taylorism and more by subcontracting to a multiplication of small, new businesses.
The East End furniture trade began to falter in the face of new factory-based mass production of furniture between the wars in outer London (and, notably, High Wycombe). Shoreditch entered a period of steep decline after WWII as factory production from brands such as G Plan and Parker Knoll ballooned. It was all but eliminated by the 1980s, and now we have Ikea.
So sure, there's still a market for craft-made furniture at the top of the market, but it's a shadow of what it was. Those tens of thousands of skilled jobs are long gone.
