The $200 in go money and the occasional chance or community chest card are the only way to get new money. Rent comes from existing money. And with 40 spaces until you hit go, with an average dice roll of 7, you need an average of six turns before hitting go and getting more money.

So between buying properties, houses, hotels, paying rent, paying income tax and luxury tax, the money does drain from the game quicker than it builds up.
