There are important differences between business and economics especailly macroeconomics.
Many, I would say most, successful businessmen for instance don’t seem to grasp that our $4 trillion mostly unconstitutional government is a HUGE (YUGE) drain on our economy. I would also say that as long as they get their share of the bribe (”subsidies”) screw everybody else. They don’t seem to grasp that in the long haul they and everyone else losses when government interferes with the free market.
There’s a difference between understanding the bottom line and understanding the “invisible hand” of the free market economy, as well as disruption it can cause from time to time which in a free market are growing pains in preparation for economic growth to the next higher level of wealth creation.
Some of the generally accepted Macro is akin to astrology. Hocus Pocus BS. I am pointing at the likes of Krugman. They couldn’t find their own asses with both hands and a map.
That said, Trump fully understands the invisible hand and sees China’s thumb on the scale. Not much invisible handing when a merchantilist’s thumb is on the scale or do you disagree?
