>employers want the best candidates but not the average candidates,
This is just flatly false. Employers want candidates at all ability levels given a competitive price.
You can be pretty bad at your job and still have a steady stream of work if you're cheap, for example. The Hacker News crowd loves to poop on these guys because we are almost by definition a quasi-professional platform, but we are far from the median take on this.
>Might also depend on your locale. Plumber in Germany might be better than SWE in Texas.
If you truly believe this, and think the difference is substantial, make a 5 year plan and move to Germany. Talk is cheap.
