If you’re a professor with a doctorate in Germany, the official way to refer to you is Professor Doctor [last name]. If you hold two doctorates it’s Professor Doctor Doctor.
Professor is also a serious and registered title in Germany. You can’t just start a school and start handing out professorships without oversight and approval.
If I was a company facing possible tarrifs I’d raise prices now. Just a little, say 5% or so. Thar way, if tarrifs hit, I can bump up a bit without being a full hit in the moment. It also means I can get the money now as pure profit. If the tarrifs don’t happen I can either keep the 5% or drop it later to look good and undercut competitors.
All wins if I charge more now. Just the chance of a market disruption can be a benefit.
