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.
Perhaps, but it’s clear we must both lower costs (fix repair laws) and provide free medical care for everyone. So fixing repair is one important step towards an end goal of health care for everyone.
Regulating the quality of repair is a separate issue from sourcing parts. The hospital and their insurance company will be well inclined to make sure that repairs are done properly, but we should let the people who own the chair (and some oversight board) decide policy for those repairs, not equipment manufacturers who have a vested interest in selling new equipment.
