I keep getting worker shortages in three of my cities. So i decideded i might try something new. i started a city with only people. no commercial or industrial.   I noticed it actually makes a profit. I suppose residential taxes. but do I need to maintain it with hospitals and police/fire? the reason i ask is, it's growing but there's no way I can keep anything other than low income people with no services. and people are moving out becuase of deaths.   Has someone else tried this before and got an idea on how to successfully do it? The only thing I can think is I could fund it from another city to keep services going.   Maybe someone has planned this out somewhere before?
