Just distinguishing Macro indicates you did not study Economics but rather Finance and Accounting, and how the government can solve monetary problems, different animal, regardless that it was inaccurately called Economics.
Take any business school where a manufacturing test case is discussed where a factory in Peoria can make widgets for $10.00 a piece. They find a factory in China that can make it for $9.00 including shipping. So the the professor says all is well the company needs to close the factory and send it over seas.
Well wait, the professor should say what are political consequences of moving that factory to China? What about moving it to a R-T-W state? Why isn't that an option? What is the cumulative affect of closing factories in the USA?
Lastly if the Company was making a 10% profit per widget made in their Peoria factory then why should they move to China ? How much of the marginal difference in lowered production cost be passed on the the consumer? All of it? If all of it then what would be the point? None of it? Then the retail price would stay the same and the consumer sees no benefit. Half of it? What would the stockholders say about that?
