What would an opportunity pipeline for white people look like? How would we detect one if it were to exist?

Why ask me? It was chneu who claimed it existed.

Edit: Yes, I made a bold assertion, based on the view from the working class and the many intelligent white people I know who were held back by not being wealthy or well-connected. For those outside the elite pipeline, it's an advantage not to be white.

If there's a pipeline I don't know about, I'd like to hear it. Point it out so more people can join the pipeline to success!

You claimed it didn't exist[1]. Presumably you had some criteria, found no evidence and then made a conclusion. What was your criteria?

1. A substantially different claim than "We have no evidence for its existence" or "We don't know that it exists".
