Not everywhere. Switzerland exists. Also cost of living is a thing so if anything US/CH just ramp up to match that. The rest of Europe has high CoL but terrible salaries. Asia has bad salaries but low CoL (on average).
According to swissdevjobs.ch[1], the top 10% salary for a senior software developer in Switzerland is 135,000 swiss franc; that's roughly $170,000 per year.
So if this is correct, then even in Switzerland, it seems like $300,000 per year would be an obscenely high salary for a senior developer.
