For example, my parents and all their friends weren't well off enough to afford private university, but majors at public university were limited by the government based on projected need with slots offered to only the highest test scores. They couldn't test high enough to secure a public university slot for accounting, art, architecture, education, medicine, and trades such as automotive repair or plumbing. So they all ended up with computer science and engineering degrees. Fully paid for by the government.
They basically treat the semiconductor industry like how the US treats its defense industry.
