"two-headed cyclops that wants to make all the money and save the world. "

He could do precisely that, as a hippie-socialist. Socialism does not advocate anti materialism. You are confusing it with early Christianity.

Socialism requires you to not monopolize means of production, divide the revenue in an egalitarian manner in between the people who work in the organization, provide a democratic governance mechanism inside the organization.

That's it.

As long as you oblige by those guidelines, you can make trillions and you will still be totallly legitimate.

Of course there are things like 'dont cheat, dont steal, dont pollute' etc, but those go without saying.
