Within the United States, for-profit businesses, not-for-profit organizations, and the government all provide services. Of these, for-profit businesses are the largest providers of services.

Most non profit based businesses are service oriented as they are not likely to incur losses this way. Product based businesses tend to cost more and that is why non profit models may not work.

Profit is the main goal of almost all businesses, even many non-profit businesses exist only to support profit businesses (e.g.- Medical Information Bureau). Running a business is an awful lot of work and if it won't support you, it might not be worth it, if its even possible.

To invest in the businesses success both to improve the businesses output and to receive a share of the profit. Some brokers buy stock purely to sell for profit.
