In countries with socialised health insurance systems any political party that threatens to take it away (or defund it) tends not to get chosen at election time, strangely enough.
Visas, different languages, and family mean that people often don't really have a choice. Likewise, most employers only provide insurance from a single provider.
Choose where you live, who you have for healthcare, who you use for childcare/schooling.
We have the opportunity to make that choice instead of having a bureaucracy making those choices for us.
