Americans are being dumb down.The American education system is teaching students what to think and not how to think. The YouTube video above is exactly correct that if United States did not continue to import PhD students from foreign countries our economy would completely collapse. The observation that freshman chemistry physics and engineering and mathematics classes are designed to fail a majority of students is also exactly correct.
We say that we want to encourage more students to seek an education in the hard core math and sciences. However our education system does exactly the opposite by discouraging most of the students. students who wanted to be engineers or scientists are going to the medical field have such a bad experience in their freshman courses today instead give up and go into the softer social sciences and then are discouraged when they have a hard time finding a job after they graduate.
I was blessed to understand from a very early age that I would need to know chemistry very well to get into medical school. I also knew I wasn't particularly good at it. So, while I was in high school I took all the chemistry that I could; even taking University chemistry courses in the summer so I could get as much background in chemistry as I could going into my poorly-taught college freshman chemistry classes.
The investment paid off. I not only graduated with a bachelors in biochemistry but I also have a masters in biochemistry and graduated from medical school and I am a board-certified emergency medicine physician. But just like the US is outsourcing our technical and manufacturing jobs, we are also beinging to outsource our medical care.
