What happened to fight so that people get paid living wages?! See, you are perfectly fine with people being slaved as long as it is not you. Well, at least now you know the robots do not cost a fortune. Also, you showed your mind is limited of processing that 20k for a robot is a lot less that a single person working for a whole year. And robots do not need to take breaks, do not need vacation or sick days. Ouuuch, for 20k even you can be replaced!
