Lobby or no lobby, with the economy in shambles and more and more people trying to get into this "recession-proof" job, employers have the upper hand. Why, then, would you not hire a bachelors prepared nurse at the same price?
More effective/safe/whatever or not, the perception among employers AND the public is: more education = better.
As a result, the BSN will inadvertently become the standard, while the ADN replaces the LPN in the hospital setting. Overall, I don't think this is the outcome of a carefully constructed plot by the BSN only crowd. But, that this is the "invisible hand" of the free market at work.
Thanks to the ****** economy, employers are able to (at least in my area) pay BSN prepared nurses LPN wages. Lucky them!
