No, the need has gone away. Take, for example, moving a few tons of concrete rubble a couple hundred feet. The way it used to be done was to have a group of men hammering it into movable chunks, and another group of men carrying the chunks by hand. Now, you just use a Bobcat. One man can do the work of twenty. Any job that requires a lot of muscle and not much brain has been more or less wiped out. That's a lot of jobs.
