There is no universe in which Chinese labor unions are even remotely the same thing as labor unions in the western-style industrialized democracies. China is an authoritarian top-down quasi-capitalistic system which means that there is no management for workers to negotiate with apart from a single massive structure that’s ultimately controlled by Xi’s government.
Contrast that to western-style industrialized democracies wherein unions are meant to use organized labor as a ballast against the power of privately owned industrial management.
It’s just not the same thing at all.
Furthermore, while virtually all modern machinery contains Chinese-made parts, it’s just a fact that in the western-style industrialized democracies, tradesmen vastly prefer power-tools made in places like the US or Germany or Japan because they tend to be much better in terms of quality and reliability and lifespan then are their Chinese-made counterparts.
Go to any big construction site in the US and you’ll immediately see that the workers prefer brands like Milwaukee, DeWalt, Makita, Hilti, Husqvarna and Bosch over the cheaper Chinese-made alternatives, for example.
