Big vocabulary, little logic or common sense.
You're making the mistake of believing that the U.S. is in fact job scarce. There are tons of jobs available all across the U.S., the issue is whether people consider themselves too good to work those jobs or not. There has been a tremendous cancer spreading across the U.S. for decades which has started at the top and moved downwards quickly. It's the "I'm special" cancer.
The U.S. also is killing itself by being hostile to foreigners who come to the U.S. and increase the countries brain pool. The greatest innovating minds of America over the past century were neither born or bred in the U.S.. We imported them. Einstein, Oppenheimer, Sergey Brin, among many others came from elsewhere.
People in the U.S. on a large scale are unemployed by choice. They're too busy sitting on their porches, drinking Schlitz, flipping through 600 channels and complaining on facebook about the shitty job market and how they can't get a job. When perfectly good jobs are available for the taking all over the place. Intelligent and creative people don't have these problems.
For example, my best friend was downsized last month.... in Florida... a place where the economical market is a disaster at the moment. It took him about 3 hours to land a 6 month contract to hold himself over while he either decides if the new place is a good new home or to look for something better. He unfortunately had to move to make due. So instead of selling his house at a loss or letting it fall into foreclosure, he rented the house out and rented himself a smaller, much less comfortable apartment until he knows what he'd like to do.
Creative people will always find a solution to their own problems. If they have to move, they'll move. If they have to work for half of what they made before, they'll cut cost and expenses until they find a way to solve the problem properly, but they certainly won't sit on the couch complaining about how the only jobs available are beneath them.
A serious government investment in robotics will create a huge amount of jobs. The only true mistake I see in this plan was that Obama is investing in America owned companies as opposed to American owned companies. NASA, NSF etc... are all great organizations, but if there's one thing they CAN'T DO is make something on time or on budget.
It would be better to go to any massive number of U.S. engineering firms who are shipping their manufacturing outside of the U.S. and offer them money instead to engineer robots to manufacture their products to keep them within the U.S. instead. When that company says "Well, we lack the specialties to design a robot", then the government can say "We can arrange for another U.S. company to design and build the robot for you. Then you'd only be responsible for finding a company which can operate it for you and paying them to use it." and when they say "We don't know how to find a company who can do that for us, the Chinese company we're using simply takes our design, builds it and drop ships it for us", then the government rep says "That's ok, we have a database of X number of U.S. companies who can acquire the raw materials and operate your robots for you".
Now, instead of a stupid plan like Obama's which would just keep the republican bureaucrats in their comfortable offices, cars and houses (it oddly, they stand to profit the most his plan), a company will now cut their manufacturing costs by keeping it inline within the U.S., a U.S. company will get a contract to design, build and ship a robot, another company will get the job of manufacturing a product using a robot based production line which will need workers, another U.S. based company would get the contract to produce the packaging (cardboard, plastic etc...) using robots operated by Americans and the rail system can receive a major boon if the U.S. provides bonuses to the robot operating companies to be located along the rail lines.
I used to run a U.S. based manufacturing business and chose NOT to upgrade to robotic assembly lines (I was too small for that) and simply had to leave the business. Now those robotic assembly lines are being run in China.
