A free market needs a constand supply of immigrants to run. And how do we spend money of legal immigrants again? if you're saying they're taking up welfare then why not just end welfar. There isn't much difference between Jose using welfare checks to buy corona compared to Joe buying bourbon.. catch my drift?
Most of the engineering majors in City College in NY(my example) are immigrants or are the children of immigrants. And you can't just "bump up" math and science if the general population has no interest. YOUR proposal would hurt engineering.

"Vying" for jobs is a good thing, as it keeps us competitive. If some joe is complaining about not being able to land a job then tough shit for him for not being able to pick out a good trade. Competition weeds out the weak. What you are proposing is welfare economics. Sorry, but a free and wild west type of market where whoever can outduke each other is what makes this country great. People, even americans may be left in the dust, but that's in the name of efficiency.
I ask you to provide statistics to back up how your proposal would save us money.. I bet the amount would be too small to make any sort of impact on our educational system.
Immigration needs to be controled to a degree where we admit people of certain nations only. Such as those of fast growing nations like China, Korea, India, Russia and others. I know that would be discrimination, but it would keep american growing and on top by stealing the brightest minds of other nations.
Your stupid proposal would make a lot of people happy, but would slow down the growth of this nation bigtime.
