I think it has more to do with Geography. When I look at the model engineer’s workshops in England... machinery is smaller and most items are dual purposed. Such as using the Boxford lathe as a milling machine and very seldom do I see the floor model bandsaw. Workshops tend to be small. Not a lot of 2-car garages in London. Of course, when I do see the English shop fully equipped, it’s usually not in London but instead it’s in a barn in a rural setting.
Taiwan appears to me to be a more urban setting with high population density. So you guys don’t have a lot of 2 car garages.
But America is a big country with a lot of space plus decent wealth for its middle class. FWIW... most of the New York City based workshops appear to be manufacturing based “home shops” in which the guy might be owner of a large manufacturer with 15-20 employees but he also has a corner dedicated for his hobbies. Those are probably guys who inherited their business and have pretty big warehouses in which they once had 50-75 employees.
Anyway, we have a lot of space in America and by and large we’re a fortunate bunch because we do have I high standard of living. I say it all the time.... even the poor are relatively spoiled in America.
