1.) That no matter how cheap we make things, it does no good if the production of those goods causes some to be so much poorer (even down to zero) that they still cannot afford it.
If that's what you meant, then we are in agreement.
2.) That we need to make things cheaper however we can, so that the poorest can afford it.
If that was your point, then well, that's the paradox. Some are poor (or poorer) because of the measures taken to produce cheap goods.
I think you meant 1.) but wasn't sure.
