Seems bring back manufacturing is load of crap
US auto industry downsized by 40+% just in past 5 years , US now makes about as many cars as Brazil(anyon ever seen a Brazilian car) a total non player in world markets .
While the US did indeed piss away a large amount of auto manufacturing over the past 25 years (thanks NAFTA!), these numbers are not correct and are in fact highly deceptive.
This graphic shows
passenger car production, and not total
automobile production. The distinction is particularly important in the US since a large proportion of private automobile sales have shifted from passenger cars (what you Euros call A/B/C/D/E/F/S/J segments, per ISO 3833) to crossover vehicles (M segment) and light trucks (what we call Class 1/2/3 or "half ton", "3/4 ton", and "one ton" trucks, without any real analogy in Europe). There are some hairs to be split at the upper end of this size range, since we typically draw a line at 10,000 lbs GVWR (the upper end of Class 2), but there are a small number of Class 3 vehicles sold and used as private vehicles (mostly to Sniper's Hide members). There are also some number of Class 1 and Class 2 vehicles used for commercial purposes, so the lines get blurred a bit. Also note that the same issue exists with reporting sales by manufacturer; Toyota and VW get into a pissing match every few years when they almost tie for 1st place in overall sales and then start arguing about whether vans and small pickups should be included (Toyota thinks they should and VW does not, for what should be obvious reasons).
In reality, automobile production in the US shrunk not by 50% but rather by about 10% over the past five years, largely since overall automotive sales have shrunk by a similar amount. Production last year ran at about 11 million vehicles; this year I'm sure will be much lower, for obvious reasons. Also note that the dollar value of sales in the US has remained relatively constant and that the dollar value of local production has actually increased (we're building fewer vehicles but they are much more expensive).
There is, however, a different story to be told from those charts, and that is the shrinkage of GM from what was once the largest manufacturer in the world to a regional player that can't even compete in every market segment in its home country. This is what happens when executive teams focus on "unlocking shareholder value" instead of building product.
