Indeed. Better economic opportunities and higher levels of general education make it hard to employ people and make money off this work at the same time. At least where I live in the US the gig platforms are staffed by people who can't hold down traditional employment for various reasons, and even with the below-minimum wage these services by and large do not really make money.

The flip side of this trend is the ubiquity of vending machines in Japan, which have the advantage of requiring no sales staff. This is very useful in a country where the labor force is shrinking and demand for low-skilled workers outstrips supply.
