Is just “all our lives will be good, or yours won’t be.”
Since there’s always some idiot who reads these posts and thinks they’re smart, no this doesn’t mean everything turns out identical or that some people won’t get cancer.
It means everyone gets enough if society has it, and gets treated fairly. It means that if a rich or powerful person gets cancer they get the exact same treatment the poorest and weakest person in society does. It means money and power can’t get you anything that actually matters: not education, not health care, not food when other people are going hungry.
“No one gets seconds until everyone has had firsts.”
The job of actual class struggle is to make it so that the rich and powerful can’t enjoy their wealth and power until everyone is taken care of and treated the same.
