My point is that strikes are predicated on the bet that the striking workers have a higher pain tolerance than the capitalists and their investors for the pain caused by a strike.
If UAW workers strike, GM makes fewer cars, people buy from competitors, and the capitalist suffers. If Kellogg's workers strike, the same thing happens: capitalist suffers, competitors benefit.
Rail strikes spread that pain to everyone. It's not the rail workers' fault, but a strike would've led to millions of layoffs, a likely recession, and severe food and medicine insecurity. The wealthy would be perfectly happy with this outcome, while millions of Americans suddenly have no income with high inflation. There is some line where the needs of those millions outweigh the needs of the thousands of rail workers. I don't know where that line is, but it exists, and I'm glad I'm not the one who has to decide where it is.
