First of all, can anyone tell me which FTA agreement written by any country of this planet are actually "FREE"?
When globalisation met corporationalism, one need to remember there are always going to be sacrificed to be made in one, both or more parties to get the agreement floating. Even bilateral trade relation favour one country over the other, people (Mostly Socialist) need to wake up and understand the purpose of "TRADE" is not fair. You can use the equilibrium of supply and demand all you want, but in the end of the day, trade relation mostly benefit one side, but as long as a trade relation can be a "Win-Win" Situation, then trade will go on. All said, probably the "Free" part of Free Trade relation is you are free to join, or not joining, that's up to you. But if you want fair trade, go become a communist.
In today world, you cannot sign a free trade agreement with the US and expect to be fair or even more beneficial to the US when the US Dollars are the nominal settlement currency in this world. For US to buy something from like Japan, Japan need to come up with a product that's worth $100 while the US only need to print that $100 note to buy them, that's probably less than 5 cents.
That's kind of grim, especially you cannot sign a free trade agreement and specifically banning export to the US, but the problem is, if you are not selling to the US, who else? Look at it lie this, US do not have the highest GDPPC but they have the largest population in term of top 10 GDP, in fact, if you compare the US with Qatar (no 1 in GDPPC) you can see the US have more than 100 times buying power than Qatar, and US alone have more purchasing power than the Top 10 combine. So where exactly can you find a market bigger than US??
Couple to the fact you cannot literally use anything to replace USD as an world reserve, IMF/WB Voucher came close but not implementable due to debt (You cannot exchange USD debt to IMF voucher), Gold standard fail when people start using gold on virtually EVERYTHING. You cannot use a commodity to act as a standard currency, as the price of that commodity itself fluctuate as the demand and supply adjust. And currently 40% of world Gold is used for everything other than investment. I can't see how government can recover nearly half of circulated gold in the market and use them as a reserve.
There is a reason why only poor country opt for Gold standard....
