I am interested to hear your reasoning on this. To me, thinking through it, I see some potential commonalities but the sine qua non of being owned as property fails. Is the argument that people have to work in general to survive, and it is the fact that they have to work what renders them as a “modern slave?” I hope not because that seems facile.

Words don’t redefine themselves.

Describing low-paying jobs as “slavery” is a metaphor. Saying “certain aspects of X are like Y” does not mean Y ‘is’ X.

But, of course, that is often why rhetoricians use metaphors and similes… to dupe and confuse people into a false equivalence.

There are slaves in this world… diluting the meaning of the word to include Uber drivers does not help them.
