Lower dollar means (for the USA) that importing stuff is more expensive, and for export, the USA will get more $ pr.unit.
Don't know where you live Brownshirt, but where I live, American stuff has been growing on the market due to the weak position of the $.
You can buy a lot of things from the USA now for quite a good price.
However when you go mechanical for instance,it gets worse, - we are a Euro-metric country, and even the TV system is different. So lots of more advanced US products do not fit so easily. If common, it's okay, - like cars.
Standards...aircraft.
Crudes like Cheerio's...yes.
DVD's, players for those, electrical gadgets etc etc, - the US does not match.....us.
The results I see from a weakened dollar is mostly big fat cars.
