Utopia does not exist. "You will benefit from it" is an absolute and can't attest to everyone's utility profiles. Even if you raise everyone out of extreme poverty, correct every ill, you are doing so at the cost to individual freedom. As a humanist, I think it is is up to each person to give meaning to their life. The freedom that comes from property ownership, the product of ones own labor, and the risks they take with that property are more valuable to me than it might be to others.

Some birds enjoy the safety of a cage, others want to fly. The closer to free-market capitalism you can be, the more choice people have to pick one or the other as they can choose what to do with the surplus from their labor.
