I wouldn't want to live or hire in SV either, but your Russian engineers are only loyal because the Russian economy has been in a tailspin since 2013. It's not that SV engineers are entitled, they just have options and your Russian friends don't.

I also don't see how wanting more female engineers could get in the way of building products so I'm not sure why you threw that in there. It's not like people are staring at the wall all day pondering diversity issues instead of building products.
