What is the cause of the trade deficitAmerica is a Wealthy nation, extremely wealthy by world standards. As others have said, the American people wish to buy more then America can produce, it's a simple cause. It does run deeper though. With a global economy, our goods have to compete globally. As a result, a host of American companies have moved manufacturing jobs out of America to reduce production costs.
We tend to focus on the Labor costs when it comes to reducing production costs. However, other countries are happy to get the work for their citizens (and the resulting income tax revenue) so they work sweet deals the usually result to low if not no taxes on that business. Also, many parts of the world do not drown their industry in red tape. We may like OSHA, Environmental, EEOC, Transportation, etc regulations, but they all cost companies money to maintain these standards, as well as administrative dollars to maintain records of these standards. Many other countries in the world do not apply these things to industry, so production costs go even lower. As more companies move out of the US to reduce their production costs to levels that allow them to compete globally, we end up with higher and higher trade deficits (not to mention less manufacturing jobs in the US).
One thing we need to consider though, is there really a trade deficit at all? A problem with these numbers is that we count trade with US company subsidiaries abroad as part of this deficit. Though, in some instances these operations abroad cause a reduction in jobs in America, trade with them is good for the America based company, the company's stock holders as well as the company's customers (who generally get the company's goods at a cheaper price as a result).
Another thing we fail to consider when it comes to the trade deficit is that as we buy goods from other countries they become economically stronger. As they become economically stronger then tend to invest more, frequently in the US. That investment means growth of US companies which means growth for our economy.
I good CATO Institute paper on this (though it is several years old) can be found
here.
Is the trade deficit good for America and why or why not?In many ways the trade deficit is a non-issue. More imports tends to mean cheaper goods for Americans, which means they can stretch their budget farther. More money going from America to other countries also tends to lead to more foreign investment in America which helps our economy.
But there are other ways we benefit. In the 1970s, the American Auto Industry was designing cars to last 5 years. They wanted American's buying cars twice a decade, as this helped their bottom line. Back then a car that was approaching 100,000 miles wasn't worth a nickle to anybody.
Because my father was an employee of General Motors for 31 years, I heard all of the anti-trade deficit arguments and nightmare scenarios. I had an "inside look" of sorts that gives me a different perspective. When the Japanese cars began to dominate the market the US auto industry and the United Auto Workers union had one voice. They were furious, this was costing US jobs, they were taking US business, etc. They were correct about the cost, but not the cause.
The reason Japanese cars were so successful with the American public was the quality of their manufacture, moreso then their cheaper cost. This resulted in the US auto companies having to vastly improve the quality of their products to compete, as well as modernize their manufacturing process to reduce production costs (my father eventually saw this as a positive, though he still wanted the US auto industry protected).
Then the Japanese car companies, in an effort to reduce the costs of bringing their products to the US market began to build assembly plants in the US. This brought more jobs to the industry in America. At the same time, the US, in a effort to be more competitive began to purchase more and more parts for their cars from overseas, reducing jobs in this industry. As a result is that these days, it is rather difficult to tell which car is actually more "American".
In the end, the issue of the Japanese car became a non-issue. As we began to see benefits from this foreign trade, some began looking for other reasons for American Job / Productivity loss. Corporate greed / shareholders demands will always be on the list. However, the exceedingly high cost of doing business in America, due to excessive regulation is right there at the top as well.
This is not to say that we should abandon regulation of Industry. Regulation has made the air cleaner, jobs safer, etc. But we could start considering a different approach. For example. These regulations change constantly, resulting in billions spent by US Businesses as they try to adjust to stay in compliance. If we consider limiting changes to regulations to once every 10 years, we could make a huge dent in this cost to American industry, without reducing our standards.
Another approach to reduce costs would be to change our enforcement approach. Instead of depending on fines and treats to keep businesses in line, we could look at financial rewards (like tax deductions) for businesses that meet the current standards. This could shift businesses approach to regulations entirely as stockholders start to see regulation as a potential source of higher profits, rather then just a liability.
The Trade Deficit has resulted in higher investment in US companies, higher standards for US goods and cheaper prices for US consumers. It has also resulted in a reduction in jobs in the US. When comparing the pros and cons I think that at worse, the TD is a non-issue and at best it is actually beneficial to the Average American.
Should the Government do anything about it? Yes and no. The government should take no action to directly try to regulate the trade deficit.

...The government has shown a propensity towards making poor economic decisions as far as I'm concerned. I see no reason for this to change. Government always looks at the short term whereas these trends are long term....
I agree totally.

The government has a pretty poor track record when it comes to economic issues and I would dread to see how badly they would mess up the US economy if they began to fumble around here.
But the ideas I listed above, for addressing the cost of doing business in America would be one area they could try to improve the economy / trade deficit / business climate in America, while also possibly reducing the cost of government.
