Private income of .047 ???

[willgamer]

Most of my cities have typical private incomes of .001 up to about .008.

However, a couple of cities have private incomes above .040.

Even moving the public income slider all the way to the right will only get up to .030. (assuming you'd be crazy enough to pay that much).

Anyone know if this is WAD?

I am not 100% sure which part of the UI you mean.

The one under Population?
That is the average private income per "private worker". Which is important in relation to the average pay of (state) workers and hiring said state worker.
The value depends on population availible vs needed in private economy.
You treasuary investment is only indirectly related to it (allowing more stuff to be built quicker). You find it listed in the Zone details.

Yes-

Population:Income >= .047

Worker:Salary usually wants to be greater than Population:Income.

The Zone Orders Salary slider all the right (maximum) is .030.

Population:Income is usually between .001 and .009.

So how can the penalty to worker opinion be avoided when the Population:Income is > .030?

What causes the Population:Income to be so high; can it be mitigated?

The Private economy increases the Pay, when there is a lack of workers. They are basically competing for workers with you. Also, I think the higher the pay the more Imigration attraction.

I have never seen the value go past 0.07 - and that was on a newly founded city.
It going higher then the worker salary salary slider is propably a bug.

So you plain and simply, have too few population. Propably by a few orders of Magnitude. And then a minor bug where the value is not properly capped.
