Not sure. When I think of the assembly line, I remember Henry Ford, not the president at the time. Airplanes, the Wright brothers, discovery of DNA, Crick and Watson, etc. So there are counter examples, but I think you have a point that politicians do get to spin the message and take credit for things.

Presidents dither around for four years but unless they screw an intern or start a reasonably large war, noone will remember them a decade later.
