Of course it's worthless. They're effectively a parasite class, they exist to direct money to themselves under the guise of directing it where it's needed. They are so far removed from any/all productive work that the whole thing's laughable.
Parasite class lends me to believe you think the finance industry holds no value whatsoever.
If you're ever in the position to run a large corporation and need to raise money publicly, you're free to sidestep the banks and do it yourself. You'll probably get a sense of the value they offer at that point.
