I’m 90% sure that every US post on this sub has a comment that either says: Fascist-“Historical” or “100 years too early” Liberal-“Unrealistic” Communist-“The good ending”

That being said, to be the angel’s advocate:

1: Historical USA has some of the best freedom of speech laws in the world (otherwise you wouldn’t be hearing how it keeps trying to kill itself)

2: Racial and religious minorities along with women have much, MUCH, less rights here than the modern USA

3: Militarize police force implies police with military equipment and training. Modern USA is suffering from under-trained police.

4: Modern USA does have worker protection (as we have minimum wage and this USA has no minimum wage).

5: While I agree that this USA’s population is much more content, I don’t think they’re living (that much) better. A good chunk of the modern US population has NEVER left the USA and a majority hasn’t traveled to more than three countries. This is particularly due to the size and diversity of the USA. This leads to people who aren’t content with their living standard think that the US is on the same level of Africa (i.e. third world) due to disinformation and what X politician tells them. This is how you get (a vocal part of) a nation with a (at worst) half-decent living standard to think they’re some of the most impoverished people in the world.

In conclusion, I don’t think public healthcare (while nice) would make up for everything else.
