A good number of French people somehow still remember (or talk with awe or anger about) the crazy early 80s, with the rampant inflation, the variable interest rates frenzy, combined with successive devaluations of the Franc Français and the moment the French government decided to follow the example of the Deutschmark and aim for what became the Euro...

Yeah when I asked (in France) about variable rates to a credit guy recently he looked at me like I was an alien. They probably still exist, but the loan-happy people won't even try to sell them, to me at least.
