This is Miller's LIFELONG WET DREAM COME TRUE.

Do you remember Paul Ryan, talking about the passage of his Ayn Rand-ian tax cuts for millionaires (erroneously referred to as "The Trump Tax Cuts" simply because he signed them?)...

Ryan claimed he "dreamed about" those tax cuts over "keggers" in college.

Since most of the people Miller knew in school hated his guts, I'm sure he quaffed most of his brewskis alone, but had similar fever dreams of deporting massive numbers of brown people without due process. And now, we're here.

So my direct answer to your question "They had no idea these shortages would happen?" is "Most likely, but they didn't care."

Zealots seldom consider consequences beyond scratching their own itch.
