Hold SHIFT and type 'FUND' for 0,000.  It will cause an earthquake
 every third time you do it, so do it before you start your city.
 
 Another tip is to set the citizen's taxes to 0%.  Then just before tax
 collection (December or November if playing at fast speed) quickly
 set the taxes up to 20%.  Then after you collect taxes, put it back
 down to 0%. This way the citizens think they are not paying any taxes.
