I don't think you can make that kind of generalization. It really depends on the organization. Ideally neither position will pull an unequal amount of weight.
Remember that in many cases, the software developer has the same kind of weight on his shoulders; some bugs and errors can cause huge amounts of lost revenue, lost jobs, etc. Software plays no small role in the day to day operations and programmers carry a lot of weight on their shoulders, especially in companies that don't have strong testing and review methods (read: almost every company in existence).
