Your perspective is really skewed here. 80k is easily enough to support multiple hospitals, specialist doctors, many dentists, and several multi hundred employee specialized companies.

I live in a city like this. We have muni employees, a hospital, some startups, plenty of non-tech jobs. There are doctors, lawyers, accountants, tradespeople, restaurants.. 80k is a LOT of people.

Side note: an hospital in Spain can be a relatively building with a few specialists, perhaps 20 people working here counting the staff. On many other countries an hospital is a huge building with dozens of specialists. The small places are "medical/care center". For sure there’s specialized jobs here too.

Clinics with 20 workers are not typically called hospitals, but rather "Centro de salud" or "Ambulatorio".

A "hospital" is a place with beds where patients stay overnight. All the countries where I have lived, including Spain, make this distinction.
