Start the process for getting Medicaid, as that takes time. Medicare may cover bits, but most will come from Medicaid. State specific programs may exist. I recommend calling her primary doctor and see if they can help you with get home health or getting her into a nursing home depending on everyone’s preference. They also might have contacts for social workers that can help you navigate getting assistance in paying for it.

Basically the plot of this story. It poses the issue of how much we value society over the individual, and if that is good or not. Would you want to live in a world that depended on the the torture of a single person. You then could extrapolate that out to societies in the real world, US and chattel slavery. the west and the use of sweat shop labor for cheap products, the Emirates and their use of migrants as indentured servants. Even tipped wages for servers in the USA, the gig economy, and things like medical residencies could be considered a minor version of Omelas. As humans, we often tolerate the abuse or exploitation of others for our own benefit, or even just out of ignorance and inaction.
