Imagine anger when you live in poverty, you work 9 hours/day (minimum, from workweek in Korea) manual labor, some people at work die or get disabilities in work accidents. As a worker you know that everyone lives from surplus you produce, the food, etc, programmers do not make food. You can only do programming since they made food for you. So as a worker, you know you do something useful, right? So you deiced to talk with your boss, you told him all this and ask for better working conditions, little less working time, etc. He fires you. On the next job, you try to not make the same mistake, you organize collectively and strike. But this time, government use force to stop the strike and kills someone of your friends. Not surprising that some workers will be very angry.

I took a morning (4am-8am) paper delivery gig, and had to "serve" rich people in big mansion, complaining they couldn't have their journal on time for a sweet breakfast coffee because you didn't dare cross a boulevard due to high speed truck driving your ways.. you get angry super fast. I'm a french dude, left leaning.. beheading is big in our history books yet it's the first time I felt that rage against higher classes. Serious shocker.

Are you arguing driving someone to suicide is then justified in the struggle for labor rights?

I’m trying to understand the point you are making?

I'm trying to explain where the anger comes from. Why do you blame the workers and not the conditions where this anger developed?

I’m not sure any conditions justify driving someone to suicide?

He's saying the strikes are justified.

Can we blame a manager for the suicides of burned out workers?

The capitalist class on the other hand is famously innocent of thuggery. It's not like the established socioeconomic relations in Korea were incubated under a military dictatorship or anything.

So did the teamsters and Jimmy Hoffa back when Nixon debased the gold standard and unions needed a workaround for the Federal monopoly on violence. (see "I Heard You Paint Houses")
