Looking at our present crisis in particular, there's certainly something to be said for taking a simplified approach based on core economic principles, logic, and intuition (all three of which this author seems to dismiss categorically). Yes macroeconomics is complicated, and yes we have created concepts in our financial systems that are beyond the understanding of everyone involved. But the basic fundamentals still apply and should still be discussed in the context of the more complex systems. The idea of long-term equilibrium doesn't disappear just because your financial system is convoluted. The foundation of macroeconomics is the aggregation of microeconomics, which comes down to people making decisions with their money. And everyone can understand that - even programmers. If the public truly can't understand the financial system, then that's a tremendous problem in and of itself.
