A manifesto for the future of work, published in 2023. The Blank Collar Equation introduced the blank collar idea: the post-white-collar worker who directs work rather than executes it. Its framework was later publicly retired by the author; the fully rewritten standalone successor is The Blank Collar (2026), whose chapter 8, "I Was Wrong About My Own Framework," explains what the earlier model got wrong and why it was replaced. This edition remains available as the earlier work, for the record.
