One of the big drivers for civil rights came from the experience in WWII. In war, there is an overarching purpose. You want to achieve your mission, and survive the war to make it home to your family. The identity of those who help you achieve those goals doesn't matter as much (very few people care about the skin color of someone who saves their life).
What if tech became less of an identity and more of just a job that you did with your co-workers not to "change to world", but just to make money?
This is not true. Color lines were reinforced in ww2. It didn't recede. Black soldiers were routinely attacked by white soldiers. And japanese american soldiers couldn't serve in the pacific for a variety of reasons ( including being killed by their fellow white american soldiers ) and in europe, japanese soldiers were essentially killed off by their own white commanders in suicide attacks. Feel free to look up the death rates of japanese american soldiers in europe. It's horrendous. Pretty much a war crime.
Race riots occurred between american white and black soldiers in australia, britain, etc. Feel free to google battle of bamber bridge or the battle of brisbane.
The civil rights movement happened because ww2 WORSENED race relations, not made it better. And with the advent of tremendous economic wealth, people were more willing to confront the race relations.
The civil rights movement was a result of more racism, not less and the wealthy post-ww2 country which provided the environment where people were willing to consider civil rights. You could argue that the post-ww2 economic prosperity had more to do with the civil rights movement than anything else.
Why is it that we forget the history of the Second Sino-Japanese War. Which cost 10-20mil+ Chinese civilian lives? Which was also an extremely grotesque human rights atrocity of an unbelievable magnitude.
