Yes. Value isn't absolutely measurable, and it often comes down to what people/groups of people identify as valuable. Donald Trump might employ a large number of individuals, but this doesn't make him more valuable than someone who owns a small local business. Production is not the sole reason for value. I'd be willing to bet that, if you did a poll on whether Henry Ford or Martin Luther King Jr. were more "valuable," it would be close.
But the bigger point is that it's really pointless to make these kinds of claims because there isn't any kind of objective quantity of value behind these figures. And when it comes to models such as Social Darwinism, you find that certain kinds of figures are valued/privileged over others. This isn't scientific, it's purely ideological.
