To get more money on campaign mode go to the colored map at the top of the screen, at the right of it there is an arrow. Click on the arrow and a series if options appears. Click on the box next to automatic buildings and auto manage taxes. Then click back on the arrow. The next year these options will take place. The computer will put the taxes right up and build all these great buildings. You still loose money from buying them but gain a lot more at the same time.
