Seriously, how does weakening a currency help exports?
Besides the fact that japan had an incredibly strong currency for 20 years while being an export leader, I think people don't understand the difference between cause and effect. The following is the example I am always given for how weakening a currency helps exports. I will use incorrect round numbers to make things simple.
Eur/usd = 2
Price of a car in euros = 40k euros
If euro weakens their currency so it is at parity with the dollar, it will now cost 50% less for americans to buy the car (it used to cost 80k to buy 40k euros, now only costs 40k).
Um. how is that any different from keeping the currency the same price, and just telling the car maker to cut his price to 20k euros?
So you either Sell something for half the price and keep your full purchasing power, or sell something for the same price and receive half the purchasing power. There is no difference. A lot of people say "yeah but now the dealer can sell more cars and get the same amount of euros!" but if the euro is worth half as much its the same effect as receiving half the price with a currency twice as strong.
I don't know how anybody can believe this crap. Either that or I am just completely insane and missing something obvious. To me it is an obvious lie that the central bankers use to justify screwing the public.
