I think the best way for architect to gain control over design, reponsibility and making profits is by a being a developer/builder. Without it all we ended up with is a set of documents which the clients wants to pay zero for it and their lawyers can find all kinds of issues with it.
There are many successful and rich architect/builders. The top 4 that came to mind over here at USA are :
John Portman (http://portmanusa.com/founder.html)
David Hovey http://www.optimaweb.com/Company/corporate_profile.html
Jonathan Segal. http://www.jonathansegalarchitect.com/
