although in this specific case in example, if the country you're talking about are the US, having access to the $500 motor only means wider profit margins for the hostpital, not necessarily lower bills for hospitalized people.
the reason the US has such high healthcare is because healthcare is both private and paid-by-insurance.
a lot of other nations have free healthcare, both in the american continent and in Europe.
Lots of countries have combined public/private systems and get equal or better results with lower per capita and per GDP expenditure than the US.
The US has expensive healthcare because it has an exceptionally poorly designed public/private system, not because it has a public/private system.
It would suck to die because the repair guy didn't solder the wire correctly.
It's really tough to draw that line though, and it's in the manufactures interest $ + lawsuit wise to play it safe.
