My word of (unsolicited) advice: think about how you come across in some of these statements and responses. There are companies like GitLab which geoarbitrage and scale the pay based on location. It is fine to do but they don't approach it in an antagonistic manner. It is neutral and pay is adjusted to cost of living. That is that.
When I read the original post and the responses, why would I even bother applying if outside the US when I will clearly be treated like a second class citizen from the start?
Maybe I'm doing more harm than good here if you end up hiding your true beliefs in future job postings. Maybe only target US devs if there is such a bias already.
One last thing to consider, lets say you can pay $150-200k USD (arbitrary number). You would likely have trouble finding talent in US tech hubs like SF, but you open yourself to near top of the market in places in Romania and Bulgaria. One competent international hire can (and will likely) be cheaper multiple mediocre local hires. Except now, the way that you present yourself will certainly scare away these competent international engineers who likely have experience interfacing with colleagues in the US to expect such compensation.
edit: To last last part, basically you are scaring away international talent, leaving subpar international candidates to apply, which then goes on to reinforce you preexisting notions. Then you trap yourself in a positive feedback loop leaving you with a limited view of the world.
