If we presume the cost of good drops to near zero if robots are creating everything, and maintaining themselves, then there will be a race to the bottom for cost. For example, if a T-shirt costs US$0.001 to make (including raw materials), then anything above that is pure profit for the seller. Suddenly people need less money to buy things that were very expensive.
I think you need to look at the portion of cost that is associated with labour and defects, and assume this will be the cost of the good until raw materials are reduced in cost as well.
Personally, no. I don't think capitalism in it current form can survive robot revolution.
