So, after introducing the euro, and everything overnight becomes ~2x more expensive, salaries will match that trajectory and eventually also become ~2x larger, almost universally no matter the job type? Did I get your argument right? I ask because I don't think this actually has been the case with pretty much any EU country.

From what I have seen, salaries will certainly adjust themselves, and they will grow, but the resulting purchasing power is going to remain lower than it has been prior to introducing the euro.
