More importantly, manufactured goods can be exported much more easily to a growing global consumer base than services (other than software) that are almost always limited locally or regionally.
Not really. It's built on manufacturing base. You need to 'service' something.
I'm pretty sure that people who aren't members of the "rich upper classes" do make use of most of those services. To take just one as an example, nail salons are actually more common in the poorer parts of town in most cities I've been in.
Fireworks booths, Halloween shops, frozen yogurt franchises, "escape game" franchises, "curves" gyms targeted towards women, edible fruit arranged like flowers...a lot of service jobs have very short shelf lives, and can really only have one or two in a town.
They both share the same limitation at the end of the day. At the end, the human being is relatively static. You can sell widget and services that free more of his time, and then you can sell widget and services that occupy that free time, maybe at a stretch you can sell him something to free the time occupied by other stuff he bought, but there is a limit at 24 hours attention span per human.
