Why does a business professor get paid more than any other professors?

Business faculty are not necessarily the highest paid in the academy. Nonetheless, on average and relative to nearly all traditional fields of study, they are highly compensated. The argument for this is usually, "the marketplace." That is, they can command more money because successful business people make more money in the marketplace. Equally important, could be, that people in business do not elect to work in universities and thus must be paid more to come. Where an English professor may dream of teaching about literature to young minds, less often a business person grows up dreaming of teaching business skills to those same young minds. This leads to many more people wanting the English professor position than the business professor position. So, less supply means business professors demand more to come. This latter scenario is at least a rival hypothesis to explain the salary variance. Maybe the true answer is somewhere in between.
