Every time I see shit about cutting edge prosthetics with near-full motion capability, controllable via muscles and nerves or whatever they even use nowadays, I'm reminded of my friend from work who couldn't even afford something beyond a simple plastic harness arm that essentially is just to make it look like he has an arm, with no utility value.

He would take it off during work because it just got in the way, but wore it out to avoid all the questions about it with randos.

Every time I see things about cancer treatments I'm reminded of a few people I knew from my parents social events that have died in the last 10 years simply because they couldn't afford the treatments. A few even got divorced to keep their debt from ruining their spouse after they're gone.

The future can be here all it wants, but until everyone has access to it, we may as well be considered a medieval society.

5e isn't that bad. Even poor people make two silver a day, and if hiring someone to cast a second level spell to cure a family member of blindness was more than they could afford, you could get so rich casting for money. But those rules are just a suggestion, and I'd probably make it so at least some cases of blindness are a little harder to cure. And you could also make it so economic disparity is much worse.
