Sure, some work is still done by hand but less and less all the time. In practically every business, machines are replacing people. In my business- the typical station now has half the number it did 30 years ago. Many job positions- film loaders, tape editors, switchers, studio cameramen, transmitter attendants just don't exist anymore. And this is true of every other business. Computers and automated machinery is doing the jobs that people use to do. Yes, it requires people to repair the machines, but far fewer than the number of people that the machine replaces. So while the number of people continues to grow, the number of jobs for them to earn a living continues to shrink. This is major dilemma for society. . . . . .
