Periodically, debate rages over the question of whether the Nazis were socialists. As a general rule, conservatives (and some libertarians) make this accusation, while left-wingers indignantly deny it. This question has returned to prominence in recent months, and it remains worth addressing. The right answer is that the Nazis were similar to socialists in backing sweeping government control over the economy, yet different from them in rejecting racial and ethnic equality. But the difference is greater in theory than in practice.When socialists come to power, they often engage in persecution of minority groups, even though this is inimical to their ideology. There are systematic reasons for this pattern, which go beyond the idiosyncracies of individual leaders.
All of this has significant implications for current political debates, at a time when "democratic socialism" is a growing movement and much of the right has embraced statist nationalist economics.
