That's not true. The median annual pay for a software engineer in the US is a bit under $100k. (The Bureau of Labor Statistics publishes good data on this.) That means most people doing software development in the US are making under $100k.

Almost anybody doing software development at a well-funded tech company is going to be making over $120k/yr, yes. But it turns out there are lots of other kinds of programming jobs, too.

And the USA is what, 4% of the world population?
