indeed - that's how our economy used to work - we used technology to increase productivity and reduce the need for labor. why hasn't anyone invented an automated lettuce picker? why bother, when migrant farm workers can be had for $30 a day. why can't I pull up to a Wendy's drive thru and enter my own order on a touch screen like ATM screen? why do we need some dude talking to me to take my order through a microphone/speaker system?
