Does a strong US Dollar hurt American Manufacturing?
Most manufactured products are sold domestically, but even so a strong dollar will (usually) cause a decline in sales and profitability of US manufacturers. The reason for this is that a strong dollar makes foreign products relatively cheaper, not just manufactured products, but all products. Therefore it becomes cheaper for person to buy, say a foreign-made washing machine compared to an American-made washing machine.

What news articles like this don't mention is that a weak dollar hurts Americans because it makes everything they buy, like gasoline, more expensive, not just manufactured goods.

The exception to the rule is during wartime. For example, as a result of World War II the United States dollar became stronger AND manufacturing profitability increased at the same time. But this was because competitors in Europe had all their factories in ruins, which is not the case today obviously.
