The Haymarket affair was a very very long time ago in what was at the time a provincial mid power nation, and despite being one of the buzzword events taught in USA high school history, I would say nobody much remembers or cares anything about it today outside of historian or activist circles where it's seen as some sort of "win".

Labor rights have been polarized through many revolutions and political upheavals in the time since then and yet...all those jobs are still gone and worldwide labor conditions in most places outside of a few small countries still aren't great for working people.

İ don't see how this is an anti labor message, quite the opposite. İ wish people would respect themselves enough to stand up for better conditions, but this starts not with bombs and anarchistic rioting like the Haymarket affair, which was very controversial in other ways, But by simply saying "no" to abuse. Unfortunately when your hungry or scared enough you will say yes to just about everything, and the powerful know this very well.
