It's somewhat similar to Germany, yes, though Germany has fewer part-time workers. In Germany (where I also live) the default options are 35 or 40 hours, though it's becoming more common to have options to work less even in "full time" type of jobs.
Anyway, I doubt the "democratic socialists" in the USA want to ban working more than 32 hours, they just want people to have the same option people have in rich European countries.
