I apologize for the length of this reply, but there are a lot of
issues you bring up to be addressed. And because of limits on the size of posts, I've divided it into two parts.
Great story but there are other angles.
What if she uses the $20 saved on an imported scarf to go with the skirt? Then all of the money is lost.
I'm not sure if you mean "lost" in the sense of tax revenue, as most of your other argument seems to be concerned with maximizing taxes. I'll deal with each part separately.
Firstly, the $20 is the retail cost of the item, which is undoubtedly marked up by the retailer, and which might also include markups by a wholesaler, a domestic importer, and possibly several types of taxes
like import tariffs or local sales tax.
For the sake of argument, let us suppose the scarf is imported from Brazil and is marked up 100% by the time it reaches a domestic retailer. This means a domestic importer would pay $10 for the scarf
originally to the Brazilian manufacturer. Does this mean $10 is lost? The answer is yes for American scarf manufacturers, or in fact any other alternative way the $10 might be spent. But it is not "lost" to
the American economy. Brazil's currency is the Real, and a dollar is worthless to a Brazilian unless he can spend it on something produced in a dollar based country. Likely, the scarf manufacturer will take
it to a bank and exchange it, and the bank in turn will trade it to a Brazilian importer of American goods or invest it in the American capital market. Either way, the dollar must be exchanged for something or it has no value.
This issue is confusing for many people because we tend to confuse money with wealth. Money is simply an intermediary exchange device that has little or no value unless there are goods and services it can
be exchanged for.
It might be easier to think of the exchange as a direct barter: Let us suppose that our consumer Jane is a hair dresser, and she takes a boat ride to the middle of the Atlantic to meet a boat carrying a Brazilian
woman who makes scarves. Jane does the Brazilian's hair in exchange for a scarf. No one has "lost" anything. Instead, two people have gained.
You must consider that when the foriegn skirt is purchased, some of the proceeds are taxed as profits but with the purchase of the American product all of the proceeds are taxed at all levels back
through the supply chain until you get to a foriegn source, typically at a third of the value of the item. So that $60 dollar skirt could generate $20 in increased tax revenue.
For a consumer, this isn't a consideration at all. When Jane goes to the store to buy a scarf, she's looking for the best quality at the lowest price in a color or style that suits her tastes. She doesn't
buy things to maximize tax revenues. Typically, the only people concerned with tax revenues are people who live off of them.
In fact, the pressure to maximize tax revenues is a bad thing.
Since the beginning of the Industrial Revolution, goods and services have tended to become cheaper (adjusted for inflation) and more plentiful. The exceptions to this are services directly provided by
the government or are heavily regulated and controlled by the government (like healthcare). This is because most government services are effective monopolies which are financed by forcible tax
redistribution and insulated from the fickle nature of consumer choice and competition. So while we see the cost of things like computers and plasma screen TV's tends to fall, the cost of public education and
healthcare tends to increase.
The constant pressure to increase tax revenues means that tax financed services are getting less efficient, the inverse of the rest of the economy.
And what if that purchaser is herself a manufacturer of skirts? An ecconomy can not sustain it self if we expect to purchase goods at prices based on wages of $1 per hour while we expect an equivalent
American worker to get paid $10 per hour. However we we try to compensate for this disparity by borrowing or, in the case of the federal government, printing more money.
Discounting the effect of unions and minimum wage laws, American workers tend to make more because America has a greater capital accumulation, a greater economic infrastructure, and American workers
tend to be more skilled. The real wealth of a worker isn't reflected so much by his wage in dollar terms as it is by the quality and quantity of goods available to him.
I'll use the example of Gilligan to illustrate this. Suppose Mr. Howell comes to Gilligan and offers to pay him a thousand dollars for each fish he catches. Meanwhile, back on the mainland, a fisherman
makes an average of a dollar a pound for the fish he catches. Does Gilligan or the mainland fisherman have the higher wage? The answer is the fisherman. Gilligan cannot take his thousands of dollars and
buy a car, a refrigerator, or go see a movie. Those items do not exist in the island economy, unless they wash up on shore by happenstance. The best Gilligan might do for himself is trade with
Maryanne for a cocoanut cream pie.
