Yes, the H1B system is grossly abused. Yes, it is a hush-hush topic in Silicon Valley and on this site.
The evidence is right there in front of us. 40 years ago, the USA was the clear leader in technology. We had no trouble producing both factory workers and tech geniuses. We were literally the envy of the world. Doctors were paid more than they are now, we made our own cars from scratch, and our press pretended not to be partisan a lot of the time.
Other countries got smart and started sending their students here, in the cases of countries like China, as official acts in their national interest.
Along with the H1B visa problem, the US has been leading in massive numbers of immigrants, legal and illegal, who are not asked to respect citizenship in their own country. Imagine China, Denmark, Iceland, or Japan doing something like that. It would be unthinkable to them.
The biggest villain is of course the citizens of the United States. They no longer encourage their children to tackle Issues that may be difficult for them or that may make them feel bad as they struggle to learn. They no longer regard the founding principles as unique and precious, which they most certainly are. They no longer view the United States as uniquely suited to help move the world forward in civil rights or ingenuity.
And finally, our political class doesn’t give a shit about citizens. Republicans and Democrats are equally rife with corruption and exist only to preserve their own power. The uniparty sends our children and our treasure to wars where no national interest is present. Our three letter institutions violate their own principles, the law, and the sovereignty of other countries routinely.
Anyone who has read the history of Rome or Britain or China can see where we are in the lifecycle of this special experiment called the United States of America. It is a tragedy not only for us, but for the rest of the world as well.
