You're right. Health insurance was originally fought for by the unions, which was why they are historically provided by employers in the US. Other nations underwent similar demands from their people, but it ended up being tied to government provision, not corporation.
With employee unions being neutered in the past century, and exponential privatized healthcare cost increases, you start to see broad swaths of employees go without insurance in the US, while other countries nationalized their healthcare to keep costs down and continue providing it to their people.
