The low US $ is making it much easier for the US to export all sorts of things like food & cars. Imports in the US just become more expensive. The OP has used a very short time frame in his rant. My interest is in the $US to $AU exchange. around 25 years ago it got to the point that $AU 1.00 was worth about $US 0.50 , Recently $AU1.00 is worth about $US 1.05 .
To put it in simple terms for some, a $AU 1,000.00 item 25 years ago would cost about $US 500.00 at the time. Recently a $AU1,000.00 item would cost about $US1050.00 . At the moment over here US new cars are relatively cheap. Japanese cars are expensive, European cars are also relatively cheap.
With the low $US your government should not need all the export subsidies that are being paid to producers, The low $US is creating a wind fall for US exporters.
