I moved abroad 30 years ago (not knowing at the time that I was actually emigrating). I was going to change from ex-pat status to local status, with all the paperwork, legal and accounting issues that come with it. There was no internet, so there were no Facebook groups to help me with any of this.

One thing I had to do was negotiate a rate with my soon-to-be ex-employer (it's a long story). The EU manager was livid saying he could get a PhD (I'm only a BSc) for 40% less than that in Houston (where I'd lived before).

He had the same clueless attitude that the aforementioned Facebook group had. Sure, you can get an engineering PhD in Houston for 40% less. So what? We're talking about an engineer who is willing to move semi-permanently to Austria, speaks some German, and work as an Austrian under Austrian law (while still of course being liable for US taxes, since we have citizenship-based taxation, not residence-based). They have to register as self-employed in Austria. Get work and living permits. Oh, and they need to know the customer and the system they have. How many of those engineers are there? What's that? Right. There is one of those. Me.

I only found out years later how pissed off he was with me, but that is another story... He thought the company was entitled to the work and all the perks that ex-pat American engineers enjoy. The customer had made it clear they were not. The customer was right.
