Richard Warren Sears started off selling pocket watches - then published a catalog full of hundreds and hundreds of products from shotguns to cocaine wine. Sears & Roebuck offered even Americans living on remote farms the chance to shop like city dwellers.

Germany's private auto manufacturers knew the project was doomed to failure. So Hitler assembled a team of designers and factory managers to enact his vision - even if that meant enslaving workers and committing murder.
