Sure, under tyranny, all sorts of evil shit are possible. The parent is explicitly non talking about slavery, or situations like indentured service where you start there. I thought that was obvious.

The parent was talking about situations where you work in a free-ish market for a period of time, then can't work (for whatever reason) and then posits that these people will be discarded—as if that's the only option, or even, the most reasonable or likely option. It isn't.

I can't think of a single culture that fits the OPs premise and description of what happens to people that can't work. Can you?
