Think about these poor postmen every time you send an e-mail. As long as we are moving forward jobs market will keep changing. Those workers are also consumers. They have cheap electronics at home made in China (which caused some local factory workers to lose their jobs), they use roads built by machines in places where humans used to do the work. They eat food from automated farms that are more efficient. It's all connected. I wouldn't say it creates losers in any class. Their/our living standard would be much much lower at this point without these kind of changes. It's up up up up DOWN up up up. (DOWN being when it hits your sector and you are not prepared for the change, and up when it hits other industries)
