Trickle down? Seriously? Even if trickle down had a positive effect on the economy (which it doesn't), technology tends to have a negative effect on employment

Trickle down? Seriously? Even if trickle down had a positive effect on the economy (which it doesn't), technology tends to have a negative effect on employment anyway. I am all for advances in technology, it increases efficiency, productivity, and quality of life. But let's face it, Amazon put a ton of brick and mortars out of business, e-mail's killing the postal service, humans are pushed out of manufacturing jobs by advances in robotics, etc...
