One interesting fact I learned the other day: IBM did 140 billion in stock buy backs in the last decade. They have a 100 Billion dollar market cap. I think that is a bit of what we have going on right now. A system propped up by injected cash, which works for now because everyone plays along. Most of this injected money goes into the pockets of the rich, who are the ones holding the assets that the FED is bailing out…
When you take into account that the credit is printed by banks out of thin air (and more so given the latest 0% reserve requirement), it's not difficult to see why the ROI surplus derived from this 'magic trick' (as Schwarzmam refers to it) is basically free money.
Corporations and financial firms with a lot of capital have access to huge loans on favorable terms; this puts them on a different playing field than small companies which don't have much capital and can't use this 'magic trick' to multiply their earnings in the same way. Earning 30% ROI is simply not possible for most individuals and small businesses.
I suspect this is the same trick which Renaissance Technologies uses for their 'Medallion fund' to hit 66% ROI per year on average... Maybe they're able to take loans against collateral owned by their other mainstream funds.
If I have $1K in cash and I can find a bank to loan me an additional $5K... If I invest that in an asset which returns just 10% per year, given the 0% interest rate environment, I can make $600 per year in pure profit on my investment... Which is 60% ROI! Anyone can be a legendary investor... You just need to find a bank which can give you 5x leverage.
These leveraged loans which yield free surplus ROI are impossible for small businesses to access. This is why they're fundamentally unfair. The efficiency advantages of economies of scale are greatly exaggerated. The real advantage is mostly financial.
And remember, that 'leverage' credit was printed out of thin air by the bank... So any extra profit which can be derived from it by an individual or company is by definition also 'printed out of thin air'... Especially when you know you're going to get bailed out every 10 years when things go wrong - There is no risk.
