Dangerous jobs pay more. That’s just the truth of it. Men are judged on the money they make, women are judged on their looks. It sucks, it’s sexist both ways, but that is the world. If more women start to work in the dangerous jobs and become electricians and sanitation, among others, they will get paid more.
What you are asking for isn’t equal pay, but equal outcome. You want social workers to get paid the same as electricians. The reality is that government jobs and social work pay vary little in comparison to trades because they aren’t necessarily as dangerous. The one part I can agree with you on is nursing. They do get better pay in this country than in yours. But, unless men in nursing and social work get paid much more than women, it isn’t a sexism issue, it is a job market issue.
