> Do you have a specific idea in mind that I'm missing? All in the US more or less pays roughly 2x or more what some other countries pay for equivalent healthcare, so there is nominally room to extend coverage while keeping costs flat in theory. In practice, it's complicated. Also 'roughly' and 'more or less' have some wiggle room for systemic differences, but it's about right.
