AFAIK, the terms left wing, center, and right-wing seem to derive from the German parliament seating order.
Aka Communists&Socialists being seated on the Left, Conservatives in the Center, Ultra-conservatives/Nationalists on the Right.
Before the internet there were around 10 eligible parties. With only 4-6 being represented in parliament. Nowadays it's around 30, eligible parties, with 5-6 being represented in parliament, and therefore a total of around 7-8% of the votes get wasted on mini-parties and another 9+% of those who barley missed the 5% qualification.
Those 630 seats/mandates are according to a candidate/mandate distribution system for all the 16 States, that make up the FRG. Before 2023 there where 735 seats/mandates - so luckily the tax-payer now needs to feed 105 less of these useless buggers.
However there are meanwhile 730 seats in the EU parliament (absolutely useless) of which 99 are from the FRG + thousands of even more useless bureaucrats and admin-staff. Then off-course there are hundreds of these "special" commissions, e.g. Ukraine advisory board, culture promotion groups, diversity promotion groups, etc. etc. etc.... where thousands or party dudes that didn't make it into the FRG or EU parliament - find their financial nourishing grounds. Not even to mention these $$ high-flyer jobs throughout UN and other world organizations.
I already advised my 9 year old daughter, to eye/strive for a Degree or Diploma in politics
BTW - the German term "Reich" as in Deutsches Reich (empire - territory) has nothing to with Reich = rich, wealthy
The Empire or Territory "Reich" derives from the Celtic word "Rig" later termed "rijk" by the Germanic tribes-ethnics. And entered the High-German language in the 11th century as "Rîhhi" & "Rihich" - and can be found in King names such as
Richard, Ul
rich, Hein
rich.
Reich aka Rig or Rijk, therefore determins a "territory ruled by someone".
Whilst
Wealthy - "aka Rich/Reich" - derives from the old high German language terms: "welag", "welîg". Therfore it is a much later association, starting off the 15th century, with people connected to the Reich aka a King or Duke running a Reich(territory) and thus being Rich aka Reich. Whilst the term "welîg" later translates in English as wealthy.
To get things even more amusing the German word for "reach" (reach me my sword) is "Reich mir", "Reiche" mir mein Schwert.
