I have a fairly unique (or at least uncommon) set of experiences: was born in Scotland under the NHS, grew up in Australia under Medicare (the public health system), and have been in the US for 15+ years now, and worked for a good portion of that at least part time or full time in EMS and seen every day the consequences of lack of access to healthcare or access in a way that is focused on acute care versus solid proactive and routine care.
