In case you are serious, engineers were most likely to lead companies until the 70s. In some countries they still are. The negotiated middle ground was engineer + MBA. But even those are kind of going out of fashion and instead there are marketing/HR/accounting + MBA filling up boards and leadership.

It's also a function of young ambitious people just following the money over time. Finance has grown and grown and grown because it's the easiest place to skim the cream. Combine that with the fact that it's transferable from company to company and it's clear why the trend. Obviously the only innovation these people are capable of is financial innovation (repackaging derivatives, ever-more-convoluted deal structures to snow people, etc), but that doesn't much matter as long as there is a sufficient base of enough new companies with actual innovations sprouting up that it provides enough grist for the finance mill.
