The relationship between macro and micro is the same as the relationship between cause and consequence, meaning macroeconomics is supposed to identify the cause, upon which microeconomics is supposed to enact consequential actions.
Except, of course, that our prevailing religion of economics is precisely the confounding of cause and consequence that leads to the grandiose and misleading depravity of reason from which this question originates.
Indeed, economics is voodoo science, not positively nor negatively describing the propensity for human capacity, and thus in its current form best be ignored lest we reinvent what economics is supposed to do.
