The Americans who are largely against those things are just racist, misogynist assholes. Largely male and almost entirely white, they want to keep marginalized groups poor. If they give them a living wage, healthcare, childcare, etc. then that gives them opportunities to better their life and get out of poverty. And that threatens their privilege. They know damn well there are plenty of women and POC who are smarter, more talented, and harder workers than they'll ever be. If they actually had to compete with them, they would lose. They have no problem giving money to billionaires to help them out, because they are mostly white guys too, so they see it as helping their own, even if they, themselves, live in a run down trailer. But ask them to help out the black, single mother with cancer and they'll say she just needs to pull herself up by the bootstraps and stop buying Starbucks.
