I don't profess to have any crystal ball into the future, or even deep understanding of the ever-evolving world of economics, but I do understand that people need jobs. Despite the increasing capabilities of today's machines, we're a long way of from sitting back and letting technology take care of our needs.
I believe in trying to help in little ways. For example, I don't use self-checkout machines at the supermarket, even if it means I have to stand in line. I don't want to help eliminate someone's job. I have similar feelings about self-serve gas pumps, bank machines, and cleaning up my own table when leaving a fast-food restaurant.
Are my efforts misguided and futile? Perhaps. Nevertheless, I believe that just because a thing CAN be done, that doesn't mean it SHOULD be done. I don't want to see wider replacement of human workers unless something else develops to mitigate further impoverishment of the working class.
