This is a good thread Nicole, even if we have beat this horse a number of times over the years.
The first thing I would like to say is that I like clean water and air just like any sensible person in the world. But, it's like George Washington said, "government is like fire it is a good thing, though it must be contained or it will burn your house down". OK, close enough.
As for toy train production, they better be thinking about bringing it home or they will be out of business in five years. The problem with these off shore factories is the lack of control of property rights as well as some local dictator taking over everything a company has. Or,as has been reported on these pages some engineer taking your lunch home with him.
The cost of shipping is becoming more of a problem then labor, not to mention the monies lost due to trying to find reliable production facilities. Who can be depended on in January of 2012 can be useless the following year because many of them are depended on one or two key people who may blow out the door with your data files.
We also have another issue that must be considered and that is the world is starting to arm like we have not seen since the early1900's. I'm not a political expert but when ever the world has built large militaries with no world power to check them we have war.
The Soviets and the West had each other, but the Soviets are no longer and we are shrinking. Hopefully I am wrong, but things do not look good if history is a reliable teacher.
In short, I feel that the big money see this coming and will try to prepare for the inevitable. So for the above reasons I would guess that toy train production will be back in about five years. It will be a trickle at first as we see in the Lionel Presidents cars, but as time passes we will see more and more of it.
A good analogy is the answer a NASA engineer gave to the question of why does man have to get off of this planet? He said,"because a sitting target is doomed"! Sooner or later the planet earth will take a mega hit from any number of natural disasters so we better get moving now.
