This is interesting because I was just exploring this idea around how all companies eventually just become banks. The example I was thinking about though was GE Capital. GE started out making stuff, then they became a bank. General Motors started out making cars, then they became a bank. Many more companies have venture arms which act like banks on a more intimate level. But still..

This makes sense as there are only so many macbooks, iphones, cars, generators, lightbulbs, etc.. to sell. Selling money is much much more lucrative.
