There are people who behave this way. They offer valuable insight and advice, as well as money, and in return get thanked in the paper, and their grant numbers printed there. But not authorship, if they didn't write the paper. If you look up "author" in the dictionary it's pretty clear. I actually wonder if journals should start offering a second list of names on the first page, or even three to allow both group-leader and technical-work credit. Has this ever been tried?
