I'm pretty brilliant at urban planning and for low wealth, and medium wealth low density cities, I can achieve paradise, perfect polution, perfect well utilized transportation systems, perfect safety, massive levels of demand, litterally nothing wrong with the city. My problem though is when I try to build up, even when I control my city into a poor state and have plenty of parks I just cant get it to zone up right. I get stuck in this stage at about 100,000 people where everyone in the city just abandones everything, and for whatever reason stop using all of my mass transit options, even without rich people I still have this problem. Someone I heard mentioned that you need all wealth types working at a job, but my cities get in that 100,000 mark and poor people wont move in even with demand at absurb levels.
Also I cant get high-tech jobs to stay in city, demand spikes and then dissapears permanently.
I'm sure there's something I'm doing wrong in the building process, any advice?
