Well, it's not like there's a whole ideology explaining how workers are exploited of the value of their labor to benefit capital, with a proven growth of hoarded wealth and shrinking middle class all while productivity is higher than it's ever been while somehow the lower classes still have as much trouble making ends meet as ever. More, probably, given the absurd level of homelessness in supposedly developed nations.
We don't need to have reached the technological singularity, we just need to have most of the energy in the universe gathered into a container the size of a microwave so we can get the replicators online. Or we need to find a way to reliably violate thermodynamics.
