Mr. Silver's comment that big international firms like Accenture provide broad experience by..working truly hard to the firm's standard (of course, one might burn out later). I was at PricewaterhouseCoopers for several years.

It helps to have several courses in technical/applied sciences to "speak" the language of a vertical industry sector. But do not forget the arts and social sciences which will give one broader understanding of people and the contexts in which they operate.

However you know, any young person doesn't well...really want their parents determining their study / career path. Your son should pursue subjects that he is passionate about with a sprinkling of courses to give him a practical edge. He may instinctively know best himself what he has been naturally gifted with.

My partner has a undergraduate university degree in civil engineering. He only did real technical engineering during the first 3 years of his career. Then he was placed in business analyst, then management roles for the duration of his career. Along the way he got his MBA and loved it. It tooks him 7 years part-time at night. He couldn't see himself ground in just doing engineering calculations/work. He worked for an oil firm for all these jobs..for 30 years.

His civil engineering degree....also has been useful for cycling advocacy..to deal the technical mindset of municipal engineering departments and find ways to negotiate better options for cycling.

His MBA...has helped loads..even now...he has to help advise his brother on acquiring a U.S. national business..so reading those balance sheets is important...
