I remember long time ago in college I was taught there ought to be a disclosure in financial statements for concentration of risks for financial instruments. I am sure Chase never did this.
Its simple mathematics. 97% accounts in savings a/cs save peanuts. The other 3% are tycoons in fixed securities and other instruments…are few but their injection is humongous.
Let me give you with a njoti scenario like you advised @Terrence_ about Web dev…those guys who have sex everyday don’t have good,thick and sticky semen…just some tears or bubbles they are depositing into coomers everywhere. If you want a good facial with big ,thick and giant cum of load…come to msee Bjur the occasional fucker.
If you paid attention to your macro economic class there there three type of pple… The land owners, the tenants and consumers. Land owners are a few pple and the control the demand and supply by flooding or hording of products or services. The tenants are like the merchants they produce/sell what is in demand consumers (populace) are at the mercy of the first two.
Land owners control factors of production hence have the wealth to bank roll a bank where the populace and tenants will bank and access banking facilities.
