I didn't compare capitalism to slavery. I said the word slavery. The first paragraph wasn't demonstrating a comparison, it was demonstrating a principle (principles are universalized, comparisons aren't). The idea that every system has positives, but those systems can still be horrifically bad.

I don't know if it's emotion that's clouding your reading comprehension, I hope it is, because then you can calm down and have a reasonable conversation. If it's not, then this conversation isn't worth having because you won't understand half of what I'm saying. Literally 50% of your last message was you misrepresenting what I was saying.

A capitalist society cannot enact socialist policies. It can enact "social" policies. These policies are inspired by socialism, and often advocated for by socialists, but the policies themselves are not socialist policies. Capitalism is an economic system where the means of production are privately owned, and socialism is an economic system where the means of production are socially owned. If private (not personal) property exists, it's not socialism. It's not necessarily capitalism (you could have other systems with private property), but in our world it always is.

Welfare capitalism, where these social policies exist, is a well established ideology that has been around for about 80 years in any serious form, and yeah welfare can be used to address some of the negative tendencies of capitalism, but it doesn't fix them. It's applying a band-aid fix, not addressing the problem. In the real world what this means is there's a class of people always working to remove those regulations and welfare because their class interests are opposed to ours.

Class distinctions cannot be solved with a regulation, they have to be solved with a societal restructuring. Our legal system does not support the idea of abolishing private property and by extension classes.
