None of it is left wing economic policy. Strength through Joy was funded by wage deductions and operating tourist facilities in occupied territories, not employer contributions.

The two things that could (at a stretch) be considered left wing social policy (Strength through Joy and maintaining the universal healthcare that existed prior to their rise to power) are fascist. Neither were for public benefit. Strength through Joy infiltrated all aspects of recreation and social life, enforced the states moral codes, and served as propaganda. The other was eugenics.

Mandatory labour programs are not economically left or right.

That leaves us with labour unions? The US allows them but Nazi Germany did not.

This is a pretty good example of how useless the political compass or scale are 🤷‍♀️
