Forces of supply and demand apply no matter how big of an economy you're dealing with. "Macroeconomics" was invented by socialists/Keynesians.
Macro Is the Government intervention on the free market
Macro is the excuse for intervention. But no matter how much they intervene, "free" market forces still apply.
"Experts" on macroeconomics are consistently wrong in their predictions. Microeconomics explains everything, even at a global scale.
