What price? The Charter of Wikimedia states the the purpose of that organization is to "Create and freely distribute a free encyclopedia in all the languages of the world" (Article III). There have been something like $40,000 in donations to date just in the first seven months of the Foundation's existence. http://www.sunbiz.org/COR/2003/0620/90039369.tif
Wikipedia will remain free, even if Wikimedia is dissolved or becomes insolvent. Why? Because all the work distributed on all the Wikipedias and related projects are released under the GFDL a license that allows liberal copying.
Anyone can create a "fork" of Wikipedia, or a mirror site (under their own name as Wikipedia is a trademark). If you want to start a homework service using Wikipedia info, go right ahead, but "the price that people pay for Wikipedia" will always be free, there is nothing however stopping someone from starting a homework service that using the Wikipedia database (note the warranty disclaimer notice on each page, however).

It used to be true, and may still be, that when you bought a print copy of the Britannica and do all the things they want you to do (like subscribing to their yearbook), the price also entitled you to submit a limited number of research requests to the Britannica. You were allowed five a year, or something like that.
Soooooo... by analogy... should the price that people pay for Wikipedia similarly entitle them to a limited number of research requests?
