Marx begs to differ. By labor theory of value Sisyphus should be the wealthiest man on Earth; unless you smuggle all the complexity and paradoxes of this theory into some ill-defined notion of "socially useful labour" (how does one measure or quantify utility?) of course...

Marx's labor theory of value very much still assumes a product of that labor to embody its value.
