An arrogant plutocrat threatens San Francisco workers with being replaced by an oppressive computer if they demand decent wages.

In the short term, the workers should simply repeat the demand, to show they are not scared.

In the medium term, they face the threat of being replaced by computers in any case, so they should organize to prohibit that. Why should stores be allowed to replace human sales clerks with computers? It should be banned by law. Until then, I make a point of refusing to use those machines, to push back against them.

In the long term, everyone should get a guaranteed income, obtained by taxing the owners of the robots. This should perhaps be conditioned on not having children; however, anyone who adopts a child should get a big subsidy.
