I provided a thoughtful example of why demand does not create jobs, did you miss it, or just ignore it?
There is no thoughtful example. Every job that ever existed started with demand. Every job. If anyone gets paid for anything, they are fulfilling a demand. How could anyone not know that?
Really? Where was the demand for the smartphone before Apple invented it?
There is constant demand for new advanced technologies in the cell phone industry. The smart phone, or hand held computer has been a dream since being written about in science fiction decades ago. A phone that could transmit images has been predicted since comic book days of the 50's.
Demand for the smart phone has been around for decades.
