That advice MIGHT make a small modicum of sense IF you are a currency trader or do alot of international travel/business.
A weak dollar is only critical when you MUST buy imported items. There is nothing we NEED which MUST be bought overseas.
OK, I hear the snide out there saying "Oh yeah? What about OIL, smart@ss!"
We have plenty of untapped oil here in the USA. The reason we buy it overseas is that it is cheaper to buy it there and ship it here than it is to pump it up from our own soil. That is due to union and environmental blackmailers that jack up the costs.
When the dollar falls far enough, it will be once again cheaper to drill/pump it here, with a corresponding rise in employment and the general economy.
You are so exactly correctomundo!!!
