I'm not sure what you're talking about, but it's definitely not the ACA/Obamacare. The ACA has has nothing to do with "free healthcare for all", and is only tangentially related to free healthcare for anybody (by its relations to Medicaid and Medicare).

If you're talking about virtually every major country besides the U.S., though, they do have something close to free healthcare for all, and it does work, and it's actually a lot cheaper for their societies than the system we have in U.S.
