Follow the money is a good start–but what matters going forward is income, and most especially, net income and disposable income. debt is important, money/capital flow is important, but when push comes to shove, all that matters is having net income/disposable income: to service debts, to invest, to spend.

Debt can be substituted for income, but not for long. Central banks have been playing a game for six long years: by lowering interest rates and making credit available, the central banks have encouraged households, enterprises and governments to substitute borrowed money (debt) for income.

This works as a stop-gap, but debt accrues a funny thing called interest that eventually eats the borrower alive. Income is (supposedly) the driver of stock valuations, the financial foundation of rental property and the ultimate arbiter of solvency: households, enterprises and governments whose income cannot meet their debt and spending obligations are insolvent and eventually declare bankruptcy.

The reality that all that really matters is income incentivizes gaming income. Corporations and their officers/stockholders benefit greatly when net income appears to rise smartly, as rising income boosts stock prices and the value of stock options.

So it's no wonder that S&P 500 Profits Are 86% Higher Than They Would Be Without Accounting Fudges. Fudging operating income with accounting trickery pays such huge dividends, why not indulge in a bit of financial flummery? The chances of anyone questioning the sleight of hand is nil, since the entire financial sector relies on systemic flummery for its profits.

Following the income leads us to wonder how the 99% of households whose income is declining in real terms can borrow and spend more every year.

Following the income leads us to wonder how OPEC oil exporters will manage with $250 billion less income in 2015, after suffering a $200 billion decline in 2014.That's a total of $450 billion of income that's vanished in a few years.
