The economy grows as businesses spend more and invest, not by “consumer spending”. GDP is a false statistic. GO (Gross output) shows it is a better gauge of the economy, as well as showing how business spending is more growth oriented than consumer spending.
That’s the really evil part about off shorng. When the factory is in Mexico it is real hard to invest in the USA economy. Buying in a new machine press made in Germany and delivered to a factory in Mexico which stamps out product destined for the USA carried in a Mexican truck is not going to grow the US economy one nickel.
