That is probably correct. The thing is, no amount of experience meeting a payroll helps you understand issues that are critically affected by the way things add up at a macro level. Businesses are open systems; the world economy is a closed system, with feedback effects that are crucial but play no role in ordinary business experience. In particular, an individual businessman, no matter how brilliant, never has to worry about the fact that total income equals total spending, so that if some people spend less, either someone else must spend more, or aggregate income must fall. This is why we have a field called macroeconomics. Unfortunately, the hard-won insights of macroeconomics are being rejected right now in favor of visceral feelings. And we’ll all pay the price.
