Profit/Income

[Servo]

Hi,

I just got the SimCity box and started playing sim city 4 deluxe I know how to terraform, zone etc. My cities are fine, but my income is low. I have reduced funding to an average level, and my taxes are %7 but I can only just pay for my city costs and have an income of only a few simoliens dollars.

What am I doing wrong?
Also, is there a video I can watch to show how to make a great city with a high profit and traffic without skipping bits and shows how to make it from start to finish?
