I remember “Bears Discover Fire” by Terry Bisson being a good one.

Omelas is the quintessential leftist short story, but if you want to consider some others:

Smokestacks Like the Arms of Gods was good.

I also liked Are We Not Men and have previously posted The Daydreamer by Proxy.

Orientation is a dark comedy corporate satire that I thought was pretty amusing.

Look up Cory Doctrow https://craphound.com/category/stories/

Should be all of his stories are to be found on his website in full. They used to be at least. I could pick one for you but a few minutes nosing around will find you something good.
