So yes when you buy a Ford share you are giving them your hard earned money which they in turn put to work investing in harder assets…like robots (or perhaps jobs for the robot company). When you only buy one share you are only contributing a small amount, individually insignificant can quickly become collectively significant.[/quote]
No, you’re not giving them a dime. You’re paying someone else who owns a share of Ford a few bucks. Only when Ford issues new shares or sells treasury stock are you providing any capital for robots.
I’m not saying that it’s an inefficient market. Only that the vast majority of invested capital has almost no effect on job creation or business expansion.
