As I said, I have one of these degrees, and have hired and worked with many people with such degrees.
First, I agree that the math and (particularly) the statistics classes are useful. Finance and accounting too, in theory, though the vast majority do not seem to internalize much. Business pretty minimal though. A 3-4 years business degree comes with less math education than the first year of an engineering degree, chemistry, physics, etc.
Also.. the majority of business degrees today allow students to avoid most math altogether... and most students do this. The whole thing is continuously moving downmarket. Most business degrees (graduate & undergraduate) are not recognised BAs anymore.
"The market" wants easy degrees with no math. They also don't want accounting or finance. This leaves just the nonsense.
IMO, at this point, most business degrees are less useful than history, philosophy, etc. Graduate salaries are about the same.
