Bernie’s right on somethings here and wrong on others.

There’s already a “best and brightest” visa and it’s not H1B. It’s O1.

That said H1B is essentially the only reasonable way for people to immigrate to the United States through employment. Most employers are not going to stick out the convoluted process to obtain an EB2/3 immigrant visa for a worker they haven’t any experience with especially since they can enter the country and immediately work for someone else.
