I thought the same thing and had even demolished some schools to create slums to meet my need for uneducated workers. But I eventually figured out that my highly educated cims were willing to work in uneducated jobs if they were the only ones available. The solution was to zone lots of residential areas and ignore industrial demand.It seems the only way to avoid this and support both high-education jobs and low education ones is to keep your education indicators in the red for both elementary and high school. Obviously, this means neglecting your people's education. I feel like this behavior isn't very realistic but it seems like that is currently the only way around this "issue."
In the population info view you can see the number of available jobs and the number of people employed, and you'll want to keep those number as close as possible. If you have too many jobs available then cims will abandon low skilled work in favour of office or commercial jobs. On the other hand, if you let unemployment get too high then crime will increase.
I use the Irish method for determining road layout. I imagine myself as a cow trying to get to a destination, then I throw some tarmac over the route. Job done.You can tell by your road layout that it wasn't done by someone from the US![]()
