Finance is a circular argument, due to the nature of finance (see what I did there?).
It's fiat currency and fractional reserve banking - the initial bootstrapping of the system is a giant 'just trust us' and 'go with it' moment for society. Debt is easiest way to grow an economy, as loaning money helps create new wealth. It allows banks to turn $5 actual dollars into $15 actual dollars, without having to take $10 actual dollars from anybody. It's magic, but it only works when people trust the system to not disappear/default, and borrow money. Without debt, there is no growth of the overall economy, there is only shifting of reserves from point a to point b.
To make my point clearer, if we have a one world communist government, and the government can dictate exactly which resource goes where and which human does what, we probably wouldn't need debt for economic growth, right? (And to avoid any confusion, no I'm not advocating for anything like that, not even within a hundred mile close).
And in any case, I'm not saying that finance is absolutely useless, I'm just saying that the focus on finance (and the return they get) might be too much for our society/ market nowadays. Thinks of it similar to the manager and developer situation, you need product manager to make a bunch of developers to work together, but if you have a 10:1 ratio of managers/developers, then you probably can use a few more developers.
