ELI5: Why in the USA are big companies NOT passed down to bloodline?

In asia, big corporate companies such as Samsung and what not are almost ALWAYS passed down to their first born son (if not, their daughter or another blood relative). 

it seems that in the USA that is not the case in a big majority of situations. why is that?

Because in the USA most big companies are not owned by a family, but by thousands of different investors who are not related to each other, and whole main interest is in hiring the boss who can make them all the most money.
