Math checked:

You produce 100.
You import net 20.
You consume 120.
You have a deficit of 20.
You need to produce 20 more to balance your trade.


In fact, I spared you guys the second order effects, such as increased replacement capital investments, increased raw material imports and population growth during the time of adaption.


CIA World Factbook (selected because no American ever appears to question it as a source):

GDP (official exchange rate):
$14.66 trillion (2010 est.)
GDP - composition by sector:
agriculture: 1.1%
industry: 22.1%
services: 76.8% (2010 est.)
.232 * 14660 = 3401 (bn)

trade balance 2010 (goods and services):
-500 (billion)

(3400+500)/3400 = 1.13
(figures vary from year to year, and look considerably worse with more 'normal' figures such as 2007 figures.)

Add material imports for 13% more goods production. Add the necessary increase in capital investments (= additional goods consumption in order to have the additional production capacity, I am not inclined to look this up again, but it's a huge deal. The last year NET capital investment was minus 1% GDP !). Add 1% population growth p.a..

Yeah, you guys need to produce 20% more, and 25% more if your economy "recovers".

What's more: Most of the manufacturing sector isn't about export. The export-capable sector needs to grow by much more than merely 20%. It's for this sector more like 50% growth required (=in the medium term not feasible without major exchange rate changes).
