Perhaps you need to think less black and white. Other companies...make money from actual products and services. Those who don't raise money by selling more stock to shareholders so they won't run out through basic operations. We call this dilution.
Let me know if I can help define anything else for you. Some companies that actually do successfully sell products and services still don't have enough funds to pay for future growth...so they dilute as well. Same definition of dilution applies to this situation as well.
