Fact: Imports are highest during booms and they are lowest during recessions.
Recession’s Silver Lining: U.S. Trade Deficit Is Down the Most on Record. Historically, there has been a surge in imports when the American economy recovered from recession. - NY Times
Let's play fill in the blank...
"Imports are ______ during booms and they are _____ during recessions."
Since you think the words "highest" and "lowest" are causal conjunctions, rather than adjectives, and you believe using those words makes the statement an opinion, go ahead and fill in the blanks with the words you think would make it a "factual" statement.
I do not appreciate your dishonesty.
Not according to the formula for calculating Gross Domestic Product:
Imports are subtracted since imported goods will be included in the terms G, I, or C, and must be deducted to avoid counting foreign supply as domestic.
There is nothing in the definition or formula for calculating GDP that suggests imports are detrimental to a nations GDP.
