What almost nobody in SV wants to talk about it the gutting of STEM in the early 90's when real wages for STEM began it's decline in the US via labor arbitrage. Of course Blank and most of Silicon Valley benefited from this, because it allowed them to get cheap, compliant labor. Eric Weinstein did a great paper on this years ago https://users.nber.org/~sewp/references/archive/weinsteinhow... . Looking at the current unemployment in STEM, which is higher than the national average, this arbitrage has just hit a point where it has killed the goose that laid his golden egg.
