Run by Production

One of the topics we discussed was the idea that Marx believes that the whole world was essentially created out of production. Essentially claiming humans are what we produce, through material things and what we make of our relationships with others. I found this not to be a completely true thought. That humans can only contribute to the world, their surroundings, by what they produce? I think that concept completely ignores the emotional side of human life, only focuses on how the world goes round, not what goes on IN the world. For example, what if a man is very successful, creates a product that doesn't represent his personality, who he is as a person, in any way. The product sells, is very popular, boosts the economy in a very healthy way. But on the inside the man is a very low shallow unhappy person. All of his personal relationships are a mess and he thinks of himself very lowly, pretty much is a waste of space that contributes nothing to anyone personal to him emotional. So yes technically speaking his productions helped the world move, the economy be stable but when he dies did he REALLY help anyone close to him? Did he lead a happy life? Is he content with helping strangers his whole life with his product that has no real value just material value?
