Fair and interesting point. I've been a programmer for a long time, and I'd say 90% of 'bootcampers' I've encountered are similarly awful. I think we're on like our 7th interviewee now and yet to find one that can write a single function compilable code on the fly.
To answer your question, it's because most people aren't. You typically work with one or two brilliant people, a buncha midrangers, then ... those.
However, when you get folks from other countries, it's typically only because your company is trying to cut costs and hires some really cheap body shop. So we don't meet the brilliant people from other countries, and are lucky to encounter the midrangers. And they don't stick around long.
I was once so excited that a person we got from said body shop
offshore was truly brilliant. Like,
a person hired as Java but happened to know C and ASM and the inner workings of the linux kernel. He asked if he could help me with a couple (harder) things I was working on, and was amazing. As you may imagine, he stayed for about a month before moving to better things. I begged my company to poach him, but our contract forbid it.
