I have a friend that incurred massive medical debts in college when their (college-provided) insurance refused to cover services rendered at the (college) hospital. The college then made all sorts of threats like “you won’t be able to graduate until this $$,$$$ bill is paid!!!”. Keep in mind my friend was only able to attend college on a full scholarship as a result of coming from a poor ESL family. They ignored all the threats, the department in charge of threatening seemingly didn’t talk to the department in charge of graduation, and to this day (5 years later) they still receive near-daily letters in the mail requesting payment. I can’t say I find my friend’s actions unethical in the slightest. Ah! The UC system…
