Science Technology Engineering and Math aren't just for business, but I think you mean that the business managers end up owning their product? MBAs seem mostly centered on the US (some in Europe, but much less in Asia) business experience. I haven't noticed that it's made the US much more successful, but it is important to have the MBA tool set to fairly get money out of the US banking/venture system. In other places…
I'm not saying Science Technology Engineering and Math are just for business; I'm saying a knowledge of business is essential to achieving large ambitions.
Business knowledge and/or MBA's are only relevant for large ambitions if those large ambitions are actually not large ambitions but rather large amounts of money instead, which in itself is without intrinsic value.
