10 grand a month for a junior is absolutely ridiculous in most of the world including large swats of the western world.
The software development world and ecosystem. I’d say all of the US, major parts of Canada, and major parts of Europe constitute a large part of software developers.
10k might be a bit too high, but it's far from "absolutely ridiculous" amounts of being too high. An employee with a 5k salary can easily cost the employer 7-8k
If you have huge salaries, yeah sure 500 dollars its okay even if you only get 5 10% more productive.
