Would I make more dollars working for Google? Sure. But I couldn't work remote. And I can't make an impact like I can here. Right now I can rapidly push out changes to help millions of people and interact with them directly, every day. That's a really rare thing and something that you just can't do or do on the same level once you're part of a much more massive machine.
Does Google make an impact? Of course, you'd be crazy to argue they don't make a massive one. But I'd argue employees 1-50 were able to do a lot more to change the world with their hours in a week than employees 60,000-60,050 are able to. I want to improve people's lives, every day. I just can't do that or be as close to the result if I did it working somewhere like Google or Microsoft. There's value in these things, to me.
It probably is wrong (1). This website in my experience gives a good estimation of how much you should earn:

Just do not put "Software developer", use "Softwareudvikler" :). I am personally quite happy with my compensation, it is a bit higher than what Stack Overflow could offer.
(1) Depending on your education, experience ...
I make almost half of what Stack Overflow would pay, that seems wrong. It wouldn't make sense that Stack Overflow could move the developers to a more expensive country and pay less.
