I am the data. I selected my major in the 1980’s based on the fact that wages for engineers and technology ( comp sci etc. ) were going up. It’s what all college student do, or should do. Did you go to college?
You come to this forum and you say, "I am the data." I believe every word you say but you are not the data you are an anecdote.
We are still no closer to knowing what to do. If you are right in your assertion that merely shutting the door would solve the problem, of course that is the way to go. But if you are wrong, we are put at a severe disadvantage against China, not to mention the eclipse of our economy.
With those stakes, don't you think we need some data upon which to decide?
