Exactly right. Countries and companies don't dump to control an industry, they dump to control an industry and thus make even more money.
Two other points on Realibrad's post. First, the displaced workers are disproportionately absorbed into the "new economy" as low wage, lower class employees, which weakens the middle class and requires more government services whilst reducing government income. This also increases the risk of collapsing into socialism or totalitarianism, as the more people without hope of success, the more people willing to give up freedom for change. Also, very little of our service sector relies on foreign customers. In fact, our service sector is becoming increasingly out-sourced to cheaper foreign countries as their citizens become more English-literate even as ours become less so.
Second, we need real wealth to purchase all those newly cheap imports. Service jobs don't create wealth, they merely move it around to make life better. There are only a few sources of wealth production - manufacturing, mining, fishing, agriculture. Most of the easily accessible valuable resources are gone, meaning increasing environmental damage to get the rest. Fishing stocks are seriously depleted; in fact we've already been fishing down the food chain, harvesting previously undesirable species as more desirable species decline to non-feasible stocks, for a few decades. We do still shine in agriculture and will for the foreseeable future, but agriculture is a comparatively low density form of wealth creation, and as it becomes increasingly a big agribusiness industry it also has the same wealth distribution problems as moving to a service economy.
At some point, we'll be faced with either selling off Hawaii and/or Alaska to pay our debts, or defaulting on those debts. And a nation which cannot supply its own needs and no longer has credit is in very bad shape.
So a few things.
First, the country that "takes away" an industry has to do it at a cost. If the firm that wanted the jobs produced a product of equal quality at a lower price, they would have taken over the market anyway. The funding that allows the firm to dump products came from somewhere, so they robbed peter to pay paul. At some point, the firm that "took away" the jobs would have to product the product at a cost that would make entry of another firm wanted to do the same. So in the long run, things would break even as they would not be able to hold off competition with out efficient production.
Service jobs are important. Its sad that people dont understand this concept better, but I guess its not intuitive for most. In explaining this, I'm also going to explain why you see growing income inequality.
You have 3 people. Person 1 is super smart and creative. People 2 and 3 are of average intelligence and are hard working.
Person 3 owns his own company. He has great ideas, but gets far more customers than he can service. Person 1 hires people 2 and 3 to do small tasks so that he can do more work, and make more money. Person 1 becomes more efficient because he can now focus on more productive things because people 2 and 3 do the less productive work. The net benefit is that person 1 has now created 2 jobs, and is making more money for himself, and for those working under him.
Now comes person 4. person 4 is a lot like person 1, and also wants to hire people to do the less productive work. Person 4 offers persons 2 and 3 to work for him, making a little more than under person 1. Persons 2 and 3 leave, and make more money.
Now, person 1 and person 4 are competing for the limited labor resources of people 2 and 3. Now, Imagine that there are now 200 more persons who are the hard workers, but are unskilled.
Person 1 and Person 4 look at those 200 people and realize the potential labor that could make them more money. The set up a model that if they pay those people x amount, they can make even more money. But if they have to pay y amount, the will make money, but not as much as if they payed X.
Person 1 and person 4 have only so much demand to fill, and with 200 people to split the demand, the wage would have to be pretty low. If there were 100 people, you would still have a cap on potential income, because that hard worker would have to bring back more value than what they were paid.
Persons 1 and persons 4 will always make more money, as what they bring to the market inherently has more value. Anyone can be a hard worker, but only a few are smart and creative. Society wants smart and creative products, and will buy it when it comes along.
Service jobs make those smart and creative people more productive. Increased productivity means more things at a lower cost. If you make $8hr in economy A, but in economy b your $8 buys you more things, and better things, which would you rather have.
