The law, incidentally, is also what makes it illegal for said capitalists to kill you for example

This only limits certain actions, not killing in general. There are ways that capitalists legally kill people all the time, like by enforcing car-centric infrastructure or with climate change or by refusing necessary healthcare in privatized healthcare systems or by evicting tenants.

Who went to jail for PFOA's?

Who went to jail after the 2008 debacle that almost crashed the world economy?

Laws in capitalistic countries protect capital. You are a fool for not understanding this.

Safety regulations are there to protect capital as well because without healthy safe workers you will not be able to run your business.

Ask yourself why safety is routed through HR in your company.

Those laws are always temporary under capitalism, just look at the deregulation happening now in the US. Meanwhile China has gradually been improving its worker protections for almost a century, with almost no setbacks.

And speaking of China, if you are a senior party member of the CPC and you use it to enrich yourself, you get executed. As usual, accusations of communist misdeeds by capitalists are just confessions.
