Almost like controlling the finance sector gives you an outsized control over the way a modern economy functions due to the fusion of industrial and banking capital into finance capital. Lenin wrote about this over 100 years ago.

Extend this thought to the rest of the finance sector - retail and investment banks control the flow of loans to businesses, investing only in firms and ideas that they believe will generate profit, while also being able to deny people access to funds at their own discretion.
